摘要
气体在不同截面通道内的流动过程中,当外界对其加热时,气体的压力将沿着流动方向下降。利用状态方程、连续方程、动量方程和能量方程导出了计算流体静压下降和总压下降的理论公式。揭示了气流的流速和加热量对静压下降和总压下降的影响。加热阻力的计算对于燃气涡轮燃烧室和各种换热器的设计具有实用价值。
Gas flows through channels of different cross-section. When gas is heated by external energy, gas pressure will decrease along the flowing direction. Theoretical calculating formula of calculating the static pressure drop and the total pressure drop was put out base on the state equation, continuity equation, momentum equation and energy equation. The effects of the airflow velocity and quantity of heat on the static pressure drop and the total pressure drop. The heat drop calculation has special significance for the gas turbine combustion chamber and heat exchanger design.
