文摘

class="label">•: A low-Reynolds version of HOGGDH model is modified for separating-reattaching flows.
class="label">•: The modifications are based on the flow field non-equilibrium effects.
class="label">•: The modified model predicts the near-wall heat transfer more accurately than HOGGDH.
class="label">•: The rapid film cooling efficiency drop due to jet lift off is accurately predicted.
