Steady-State Fluid-Solid Mixing Plane to Replace Transient Conjugate Heat Transfer Computations during Design Phase

The demand for increased turbomachinery performance, both, towards higher pressures and temperatures, leads to high thermal-loads of specific components can critically affect mechanical integrity. In the particular case rotating-disk configurations, like back-side wheels or in cavities, a very efficient way cooling is jet impingement. An example this situation are pressure-ratio turbochargers, where impeller disk (back wall) introduced achieve tolerable thermal loads. From physical point view, impingement on rotating wall generates an unsteady heat transfer situation. On other end, accurate values time-averaged temperatures would be sufficient design purposes. general, obtaining circumferentially solutions requires transient analysis conjugate (CHT) process account mean effect solids. Such computationally expensive, due difference information propagation time-scale solid fluid. paper, new approach directly compute (i.e., steady-state) temperature distributions CHT problems presented based adaption well known fluid-fluid mixing plane approach.
