Description
HVAC CFD Simulation Training Package, 10 Practical Projects for ANSYS FLuent ADVANCED Users
HVAC CFD Simulation Training Package includes 10 practical exercises in the HVAC field by ANSYS Fluent software for ADVANCED users.
Room, Building, and Office HVAC
In practical exercise number 1, the split air conditioner’s movement of the heated airflow inside a room is investigated. The air inside the room is heated using two split coolers and is distributed inside the office with people using two fans. A realizable k-epsilon model is exploited to solve turbulent flow equations, and the Energy equation is activated to calculate the temperature distribution inside the computational domain. In project number 4, steady airflow is investigated between two 3-bladed series fans rotating at an angular velocity of 300 rpm applying the Frame Motion Method (MRF). The rotation of fans generates air suction at the inlet boundary with a flow rate equal to 2.95755 m3/s. The air velocity reaches values up to 25 m/s on the domain centerline. However, the maximum air velocity in the domain equals 47.05 m/s captured downstream of the first fan.
Radiation
Practical exercise number 5 of HVAC CFD Simulation Training Package, steady airflow enters the domain from the bottom of the computer room by several inlets and exits the domain from several outlets on the ceiling considering Radiation heat transfer. This new air conditioning method is commonly used in office environments. This method increases energy efficiency since the flow naturally goes upwards due to density difference and buoyancy body force. Problem number 7 simulates the heat transfer inside a mosque by applying the radiation model. In the present case, it is assumed that heat transfer takes place in two modes of convection and radiation. In fact, the building’s indoor heating source is powered by solar energy, and a heat source is used on the mosque’s ground floor.
Problem number 8 HVAC CFD Simulation Training Packagesimulates the airflow through the space between the two walls of the double façade of the building. To move the airflow upwards in this space based on the density changes caused by the pressure and temperature changes, the boundary condition of the pressure equal to the atmospheric pressure at the inlet and outlet of this space has been used. The main cause of temperature changes is the presence of solar energy on the plates of these shells; therefore, the radiation energy model of Discrete Ordinates (DO) and the solar ray tracing model have been used.
Industrial HVAC
In project number 2, the ventilation system of a ship’s engine room is investigated. This room has 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, and the injected air (300 K) is responsible for cooling the engine room and lowering the temperature of engines and motors. Problem number 3 simulates the airflow around several generators in a generator room and the effect of a set of fans on them. Generators are generally mechanical devices that can convert mechanical energy into AC or DC electrical energy. This process of generating electricity is done by changing the magnetic field of a conductor.
CORONA: Operating Room / Clean Room (HVAC CFD Simulation Training Package)
In case number 6, the operating room HVAC considering the equipment and persons within it, including the doctor and patient, is simulated using an air conditioning system. The system uses a laminar flow to purify the operating room’s air and a linear flow called an air curtain to prevent contaminated flow into the fresh air. The source of the contaminants and excess gases is assumed on the patient’s body.
Problem number 9 simulates fresh air flow through the air conditioning system inside a patient’s cleanroom, considering the CORONA virus. We place the patient on a bed in a room with a high temperature on his body and constantly spread the CORONA-virus particles by breathing through his mouth into the room’s interior. The goal is to use an air conditioning system and keep the fresh air flowing continuously inside the room to remove contaminants from the patient’s mouth through the outlet vents, and the room environment should be purified in terms of pollution, and a balanced and pleasant temperature should be provided for the thermal comfort of the patient inside the cleanroom.
Finally, in practical exercise number 10 of the HVAC CFD Simulation Training Package, based on the CFD method, an attempt has been made to simulate the respiration of viral air from the mouths of several patients carrying coronavirus in the aircraft. This model includes a computational domain in the form of an airplane and seats inside it, on each of which a passenger is modeled. For each of these passengers, a surface is defined as the mouth as the source of respiration and transmission of the coronavirus.
