LARGE EDDY SIMULATION OF POOL FIRE OF A DIATHERMIC OIL

In this work, the flash point (FP) of a diathermic oil used in the circuit of a packaging industry was measured. It has been found that the oil is operated at temperatures ( 250°C) higher than the FP ( 210°C). This issue increases the risk of fire. In order to estimate the consequences of a pool fire involving diathermic oil, a CFD model based on Large Eddy Simulation (LES) was developed. Numerical results have shown that, under the simulated conditions, the height of the fire is such to reach the roof of the boiler room.
