The only cooling mechanism is convection. The axial distribution of the HTC is therefore highly uniform, resulting in smaller and uniform temperature gradients within a cylinder, as shown in Figure 11.See all results for this questionWhat are the errors in the gas quenching model?Gas quenching: errors in calculated core and near-surface temperatures. These errors are calculated in Phase 2 (model verification), and refer to the original measured temperatures, so they include the initial smoothing of measured near-surface temperatures, numerical solution of the HCE [4], and the final smoothing of calculated .See all results for this question
