The fully developed turbulent flow and heat transfer in a plane channel at a nominal shear Reynolds number of 180 is studied via the direct numerical simulation technique. A linear velocity-slip boundary condition is assumed on one of the channel walls, whereas the classical no-slip condition is imposed on the other wall. The heat transfer at the slip wall is assumed to occur with and without temperature jump, whereas a classical first-kind temperature boundary condition is assumed on the no-slip wall. Various statistical quantities are shown and discussed. It is observed that the velocity fluctuations are attenuated in the proximity of the slip wall but they are amplified in the vicinity of the no-slip wall. The behavior is somewhat different for the temperature fluctuations. For the case without temperature jump, the temperature fluctuations are amplified near the slip wall, whereas they are attenuated close to the no-slip wall. For the case with temperature jump, the modifications of turbulent heat fluxes are more dramatic and they decrease by increasing the amount of wall slip. In general, the velocity slip condition will result in an enhanced heat transfer if no temperature jump is taken into account. This behavior is reversed when the temperature jump at the slip wall is taken into account. The budget of temperature variance is shown and discussed for the case with temperature jump.

通过直接数值模拟技术研究了在名义剪切雷诺数为180的平面通道中充分发展的湍流和热传递。在其中一个通道壁上假设线性速度滑移边界条件，而在另一通道壁上施加经典的不滑移条件。假定在有和没有温度跳变的情况下发生在滑移壁处的热传递，而在无滑移壁上假定有经典的第一类温度边界条件。显示并讨论了各种统计量。可以看出，速度波动在滑移壁附近减弱，但在无滑移壁附近增大。温度波动的行为有些不同。对于没有温度跳跃的情况，温度波动会在滑移壁附近放大，而在靠近滑移壁时会减弱。对于温度跃变的情况，湍流通量的变化更为显着，并且随着壁滑量的增加而减小。通常，如果不考虑温度跃变，速度滑移条件将导致传热增强。当考虑到滑移壁处的温度跳变时，此行为将被逆转。显示并讨论了温度变化情况下温度变化的预算。如果不考虑温度跃变，速度滑移条件将导致传热增强。当考虑到滑移壁处的温度跳变时，此行为将被逆转。显示并讨论了温度变化情况下温度变化的预算。如果不考虑温度跃变，速度滑移条件将导致传热增强。当考虑到滑移壁处的温度跳变时，此行为将被逆转。显示并讨论了温度变化情况下温度变化的预算。
