Introduction

A marine engineer is responsible for operating, maintaining, and repairing all major mechanical and engineered equipment onboard a ship after studying marine engineering (also known as maritime engineering). Propulsion mechanics, electrical and power generating systems, lubrication, fuel systems, water distillation, lighting, and air conditioning systems are just a few of the mechanical systems that aid in running any vessel.

People who have studied marine engineering (maritime engineering) are responsible for various tasks, including Mechanical system monitoring and maintenance. Each engineer on board is assigned specialized machinery and procedures for maintenance and monitoring. All engineers are responsible for their machinery systems, and each engineer must ensure that their equipment is operational. Marine engineers are also responsible for the maintenance of the deck machinery. Proper record-keeping and maintenance planning — The engine room department works together to ensure that the maintenance plan maintains all mechanical systems.

How to Improve Marine Engineering using CFD Simulations?

In today’s rapidly growing digital technology age, it’s critical to figure out how to apply it to the challenging ship design process. Computational Fluid Dynamics (CFD) has become an appealing method for getting important insight into the hydrodynamic properties of surface vessels, riding the tide of fast advances in High-Performance Computing. CFD, especially RANS-based CFD approaches, uses Navier-Stokes equations to simulate fluid flow while accounting for its nonlinear character. In terms of physical modeling, it is a comprehensive approach that allows very little chance. This makes it extremely precise and accurate, but it also makes it computationally costly compared to typical engineering tools. It also necessitates the employment of a highly qualified individual.

Computational Fluid Dynamics (CFD) is a flexible and powerful engineering technique that may provide new levels of detail for various flow phenomena.

There is also open-source CFD software available; however, it is difficult to use and requires a specialized user. However, more and more organizations are now offering consulting services that include simulations for design firms. This is a fantastic setup, and it fits in perfectly with the concept of work division. The cost, quality, and speed of these services are all improving, and they’re now where they may be employed in the early stages of design.

 

To mention a few, extreme wave impacts, green sea loads, slamming, sloshing, seakeeping, flooding, coarse-keeping, and maneuvering. The method’s universality is the quality of CFD that permits it to be employed in such a wide variety of applications. At its most basic level, CFD makes no assumptions regarding the flow phenomena in question, such as wave steepness assumptions, single-valued free-surface elevation, irrotational flow, tiny changes in the wetter surface of the hull, and so on. As a result, the approach may be used to solve a wide range of issues.

 

CFD on Simulation of Towing Tanks

Towing tanks have given naval architects a dependable way of estimating a ship’s performance at sea since the first commercial ship basin was commissioned in 1883. Towing tanks are utilized for both resistance and propulsion testing. Self-propelled ship models are used to establish how much power the engine will need to deliver to attain the speed specified in the shipyard-shipowner contract. Chemical reactors may be designed using CFD fluid-flow patterns and temperature fields and can be approximated using numerous conservation equations relating to fluid motion and energy.

Computational Fluid Dynamics (CFD) has long been promoted as a viable alternative to tank testing, offering a “numerical” model basin that could, in theory, be used much sooner in the design phase, providing naval architects with a stream of engineering data to influence and improve the design. CFD also has the distinct benefit of delivering accurate results regardless of the scale used to calculate them.

By offering a more refined and efficient design that requires fewer revisions to satisfy contractual commitments, CFD simulation may be utilized to decrease the volume and expense of physical towing tank testing. It’s also true that towing CFD has completely replaced tanks in some areas of the business, like the design of high-performance vessels competing in America’s Cup.

CFD Usage for Propulsion Systems

CFD is widely utilized in the maritime sector, either alone or in combination, to solve various hydrodynamic issues. The ocean environment causes a ship’s speed to decrease and its propulsion power to rise.

Prediction methods are constantly being developed and refined to account for the impact of waves on power-speed estimates and the consequent propulsion-related energy consumption. The capacity to handle variable shapes and precise information about the near and far flow fields would greatly aid in improving the hull for a more efficient or novel design.

Ship Engine Room Ventilation System using CFD

Electric motors provide the power required to start compressors, pumps, fans, and other equipment on ships. The engine room takes up the majority of the ship’s interior area. Because of the large number of equipment in this area, it is vital to investigate how heat is transmitted. One of the essential aspects of the engine room and ship architecture is the optimal design of an air conditioning system to feed combustion air within equipment and control temperature and humidity inside this area.

Engineers and researchers have constantly attempted to improve the design of the ship’s air conditioning system by proposing new approaches. Simulation and study of the ventilation system in the ship’s engine room can aid in developing new and novel approaches.

This post just looked at a few CFD applications that can help improve Marine Engineering. The Marine business has a plethora of CFD applications, ranging from a Fish Cage Floating on Seawater to the modeling of a Water Turbine and Jet Ski to assess velocity and pressure around objects, all of which are key challenges in the industry.

Most aspects of the marine industry rely on fluid dynamics. Although physical prototypes are required for later phases of development, CFD studies may significantly speed up design and optimization in the early stages.

MR-CFD Services

The MR-CFD team conducted numerous outsourced simulation projects for industrial and research Marine Engineering applications. With several years of experience simulating various problems in various CFD fields using ANSYS Fluent software, the MR-CFD team is ready to offer extensive services of simulation configurations. For example, a Fish Cage Floating simulation on Seawater is freelanced and carried out to study the solution’s parameters.

Fish kept in cages is a relatively recent issue in fish farming. Various instruments, such as nets, can be used to divide a portion of the Seawater, lake, or water behind the dam from the surrounding water, and then the fish can be confined in this area.

The advantages of these cages over fish ponds include cheaper investment costs, the ability to extend or move them, the fact that the fish are contained in a small space and require less energy, the option to utilize natural Seawater, and the use of natural and live food. We may set these cages on the seawater flow in a fixed, floating, submerged, or other location. The floating cages are designed to hold the mesh in place by a certain ring or frame. We create a computational domain of Seawater in this simulation, which includes air and water with a specified quantity of water.

The following research uses ANSYS Fluent software to simulate water flow on horizontal axis water turbine (HAWT) blades, intending to determine the velocity and pressure distribution on the wall of the blade. A cylindrical region immediately around the blades and a huge space around the cylinder make up the area around the blades. Water flow in the wide outside area is expected, while the blades’ rotational motion creates the rotating flow in the cylindrical region surrounding the blades.

One of the most typical phenomena we see is the flow around floating objects on a fluid. Examples are boats, ships, jet skis, and other moving vehicles. When two fluids come into contact, phase change and the impact of one phase on the other is always a factor to consider.
