Complex heat transfer coefficient and resistance lossof the moving gas inside system are important parameters to evaluate the characteristics of heat exchanger.
综合传热系数和系统内气体流动阻力损失是评价换热器性能的重要指标。

With graphite particle content increasing from 5% to 20%, wear weight-loss and friction coefficientof the composites are obviously declined, greatly improving wear resistance of the composites.
Under the same wall heat condition, with the increase of momentum correction coefficient, viscosity lossof the nozzle increases, but thrust and specific impulse decrease.
