Air Ventilation

Project number 1 examines the performance of fan-driven airflow inside an Office for HVAC operation, including a computer and four lamps. On the upper part of two walls of the office, we install two fans to transfer airflow into the office. We also assumed that the doors and windows of the office have convection heat transfer by ambient air. The problem goal is to investigate the effect of blown airflow on the components and people in the office. Also, we simulate the influence of airflow on the heat sources applied in the model.

In project number 2, the 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 space 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. It should be noted that the Ideal Gas equation is opted to capture the changes in air density due to temperature change.

In project number 3, a Fan Heater’s performance and the movement of the heated airflow inside a room are investigated. The air inside the room passes over a heater placed on one side of the room and a fan is responsible to push the heated air into the room. It should be noted that the ideal gas equation is opted to capture the changes in the air density due to temperature change.

In project number 4, which has been done by CFD numerical simulation method, the Air Ventilation is simulated in a GREENHOUSE with two small fans with a radius of 5 cm that rotates at a speed of 100 rad/s. The heat flux of 250 w/m^2 defines the lower wall of the greenhouse, and the sidewalls are defined by a coefficient of 30 and a free stream temperature of 300 K due to the thermal interaction with the outside air convection. In this simulation, the Radiation model is also activated to calculate the effects of radiation on heat transfer.

In project number 5, a Fan Stage is simulated with periodic boundary conditions. The fan stage is a common apparatus used for creating steady airflow in industrial applications used in the cooling process of newly painted body parts. Two sections are involved Rotor and Stator. Rotor, which has a built-in blade, rotates with constant angular velocity and leads air to enter the stator region with high velocity. Blade within the stator alters the flow direction to force it to exit the stator approximately normal to the outlet surface. Rotor domain rotation is simulated using an MRF module with an angular velocity equal to 1800rpm. The stator domain is fixed.
