Air Flow in Room of Boarding House Simulation Using CFDSOF

Simulation in Boarding House

A simulation using CFDSOF has been conducted for knowing the air flow in my room in my Boarding house.  The following picture is the domain of my room.

     


The ventilation and opened window are set to be inlet, while the door is outlet, like shown in the following picture of “grid permukaan”.

“kondisi sempadan “ for the case above is:

-          The opened window normal velocity is 4 m/s while for ventilation is 3 m/s. This is due to the filter installed in the ventilation.

“Konstanta fisikal”  for the case above are:

-          Density = air density = 1 kg/m³

-          Viscosity = 10^-3 Pa.s

-          Operational pressure is the atmosphere pressure.

“Atur model” and activate the “turbulensi” and activate the “K-Epsilon”.

The Result

The iteration is converge at 1364^th iteration like shown in the following picture.

The graph of the “residu” is shown by the following picture.

The following figure shows the velocity vector distribution of the air flow.

We can see that almost all of the space of the room is passed by air. It’s clear to know this by looking at the following picture.

However from the above picture, the air that pass the bed is not much. So, it’s not so healthy for me when I spend my time in the bed. But usually I direct a fan to make the air flow much enough.
