A finite volume ,model, was developed to simulate transient ,heat transfer, in firefighters' ,protective clothing, during flash fire exposure. The ,model, domain consists of three layers of fire-resistant fabrics (outer shell, moisture barrier, and thermal liner) with two air gaps between the ,clothing, layers, the human skin, and the air gap between the ,clothing, and the skin.

The cool water “extracts” the heat from the body (in heat transfer, the hot always moves to the cold), and then removes it from the body through evaporation. This works as long as the garment is wet and cooler than the body. When it warms up, all you have to do is wet it again with cold water. This method can be used indoor and outdoor.
