Witrynaobtained by imposing a convective heat transfer coefficient distribution on the internal wall side . Often D is the zero, first or second derivative operator: in this work the second derivative formulation was chosen in order to preserve local variation of heat transfer coefficient distribution. Under this assumption the object function becomes: WitrynaAfter that, convective heat transfer and radiative heat transfer in a gas-solid two-phase flow are described in detail. Finally, the method for calculating heat transfer in a fluidized bed is introduced. Both the influence of heating surface structure/size on the heat transfer and the gas side heat transfer coefficient in a CFB boiler are ...
