Boundary condition for ventilation problem

Respected sir,
Iam working as a Professor in an engineering college. so far i had published many papers in national and international conference in the topic of flow analysis in pump using ANSYS. now i am analysing the ventilation in room. the ventilation is purely based natural type. Please suggest the possible boundary condtions for the domain. my doubts are as follows: 1. The atmospheric air is existing outside the room. if i give atmopheric pressure for the window inlet,then how i have to calculate total pressure. 2. What about the heat generation from the floor. if the heat generation value for a human body is 120 w/m2.then what is heat generation value i have to give for the total floor if four occupants are present. 3.If possible please give any tutorial for solving the flow problem in room . I am eagerly waiting for your reply. |

1. Give atmospheric pressure for inlet boundary, FLUENT will calculate total pressure automatically based on model height and air density.
2. You will have to assume a surface area for the human body. A cylinder of 5 ft high by 2.5 ft diameter is close. 3. Nothing I have seen in the FLUENT manuals. |
