Using the ΔT method, each loop in magnetic field is recorded at a given value of thermal gradient, that is the temperature difference detected by the two thermocouples over the thick- ness of the LSSE sample. For the heat flux method, we record the LSSE electric field at given values...
My question is: how does the post processor of Fluent calculate radiation heat flux? Is it with the assumption that the surrounding is at the "Operating Temperature"? In other words, is that the actual heat flux? Thread ToolsSearch this Thread ...
The values of hot gas temperature and heat transfer coefficient for the front face of theEXPOSEDcase are shown inFigure 15. These values are used to calculate the convective flux from the surface. The heat transfer coefficient is relatively smooth, but the hot gas temperature fluctuates. The cub...
where N is the material flux, i.e. the number of moles passing through a unit of surface area, a, and D is the diffusion coefficient. The negative sign on the right-hand side indicates that the diffusion process occurs towards regions of lower concentration. Fick's first law applies to ...

The effects of heat flux and fin size on the phase change material and capacitance were investigated. With a heat load of 1,600 W/m2, they discovered that the presence of transverse ribs could have decreased the source temperature by more than 1,200°C. Silva et al. [11] numerically ...

Tcl is obtained by breaking down the heat flux through the clothing (see Equation (25), which is a function of the skin temperature (Tsk) and the thermal resistance of the clothing (Rcl). Rcl takes a value equal to 0.0558 due to ASHRAE standardised values [66].(25)C+ΔRL=Tsk-TclRcl...
