At low Biot numbers, meaning that cooling performance dominated over the conduction effect, the temperature distribution became more uniform due to higher conductive heat transfer. The total cooling effectiveness was strongly related to the Biot number of the plate, and the correlation between total ...

As a result, there is a higher evaporation of droplets, meaning that less energy will be taken away by the less efficient vapor-wall convective heat transfer. Therefore, the wall temperature will be lower for finer grids. Actually, the enhanced evaporation also increases the convective heat ...
Cooling channels in many hot-section turbine airfoils have ribs machined on their walls to augment heat transfer, and they make multiple passes through the airfoil, meaning sharp turns are present. In order to extend the CHT methodology to these more complex internal cooling configurations, work ...
It was seen that when considering a case similar to 伪_A=0, meaning that heat transfer on the compressor side is considered to occur only after the compression process, significant temperature could build up in the impeller area of the compressor housing, indicating the importance of the pre-...
curvature are correctly attenuated, and the wall temperature predictions are much closer to measurements.; Cooling channels in many hot-section turbine airfoils have ribs machined on their walls to augment heat transfer, and they make multiple passes through the airfoil, meaning sharp turns are ...
This approach has been avoided in the past, perhaps due to the difficulty of interpreting the physical meaning of a negative or infinite h, and by extension of a negative or infinite Nu. We will return to this point in Section 2.2. Instead, to circumvent this problem and to capture the ...
Discussion of whether apparent bifurcation/chaos in the solution has meaning in this class of problems is discussed.doi:10.1016/j.jqsrt.2017.04.018Howell, John R.Cockrell, ErnestChair Emeritus, MemorialJournal of Quantitative Spectroscopy & Radiative Transfer...
A zero gradient boundary condition is applied when the flow is positive, meaning the vapour/liquid leaves the domain. When we experience an inflow, the velocity boundary condition is calculated from the boundary condition face normal component of boundary cell mass flux. However, water cannot enter...
In practice, we solve the state equations in a sequential manner, meaning that the Navier–Stokes equations are solved first, and that the resulting velocity is used to solve subsequently the heat equation. Due to the reversal in space–time directionality (and thus in causality), the adjoint ...
