Computation of convection heat transfer coefficients on the specimen of a cone calorimeter using CFD

초록

The heat release rate of a specimen exposed in the horizontal orientation to controlled levels of irradiance with an external igniter can be measured with cone calorimeter [1]. To analyze charring pyrolysis process in the specimen numerically, we need the boundary energy balance equation on the surface of the specimen as: . The convection heat transfer coefficient is used for convection heat transfer between the surface of the specimen material and surrounding air. Convection heat transfer coefficients on the specimen of a cone calorimeter are obtained using a commercial CFD program, FLUENT 6.3 [2].
