Description
Engine Room Ventilation System of Ship, ANSYS Fluent CFD Simulation Training
This simulation is about a ship’s engine room ventilation system via ANSYS Fluent software.
On ships, the power needed to start compressors, pumps, fans, etc., is all supplied by electric motors. The engine room occupies the most significant space allocated to the various parts inside the ship.
Due to the accumulation of all these machines in this space, studying how heat is transferred is necessary.
The Optimal design of the air conditioning system to supply combustion air inside the equipment and regulate temperature and humidity inside this space is one of the most important points in the design of engine rooms and shipbuilding.
Engineers and researchers have always tried to optimize the air conditioning system’s design for ships by presenting new methods. Simulation and analysis of the ventilation system related to the ship’s engine room can help better explore new and innovative methods.
This project’s room consists of an air inlet (mass-flow type, 35 Kg/s) and two pressure outlets. The diesel engines and motors generate heat (12500 and 8333.333 W/m3, respectively) while working.
The injected air (300 K) is responsible for cooling the engine room and lowering the temperature of engines and motors.
The geometry of the present model is drawn by spaceclaim software. The model is then meshed by ANSYS Meshing software. The model mesh is unstructured, and 706053 cells have been created.
Engine Room Methodology
In this simulation, the energy model is activated because the primary goal of this project is heat transfer. A distinct volume is considered in the modeling to define the heat generated by motors and diesel engines. It is assumed that each volume produces a specific amount of heat.
A heat source must be defined in cell zone conditions to determine the amount of heat; That is, a certain amount of energy is produced per unit volume.
Engine Room Conclusion
After simulation, the contours of temperature, velocity, and pressure are obtained. Also, streamline and velocity vectors are obtained. Streamlines indicate that the cooling air of the ventilation system enters the room and is well distributed in the space.
The temperature contour also shows that the motors and diesel engines have a high temperature, and cold air goes to the surface of the motors and engines to cool them.

Derek Wolff III –
The simulation sounds comprehensive. Would you be able to describe how the simulations account for the temperature difference throughout the engine room—like how it varies closer to the engines and further away in the corners?
MR CFD Support –
The temperature distribution throughout the engine room is calculated using the energy equation as part of the simulation. As the hot air emitted by the engines and motors rises, cooler air is brought in through the intake to replace it, resulting in a temperature gradient. Closer to the engines and motors, the temperature is higher and decreases as you move away. Detailed temperature contours generated by the simulation show this variation and allow understanding of how effectively the ventilation system cools different parts of the engine room.
Prof. Kaden Fritsch V –
Does the simulation take into account the natural convection that occurs in an actual engine room or is it purely focused on the forced ventilation system?
MR CFD Support –
In this simulation, the focus is primarily on the forced ventilation system to cool the engine room. Heat sources from motors and diesel engines are predefined and the simulation studies the effectiveness of the air conditioning system injected by the mass-flow inlet in reducing these temperatures. While the simulation includes heat transfer, which could include convective effects, the primary mechanism being modelled is forced convection through the ventilation system.

The ability to customize this simulation for different types of ventilation systems is a significant advantage!
