flow deflection meaning in English

气流偏转

Therefore , it is necessary to take suitable measures to alleviate the influence of flow deflection on the heat - transfer performance of the condenser
在管束布置时，应当采取相应措施减小流场偏斜对凝汽器传热特性的影响。
The numerical results show that because of the temperature variation of cooling water along its flow direction the heat load of the second - pass tube bundle is lower than that of the first - pass tube bundle , which brings about the steam flow deflection and then the deterioration of heat transfer
计算结果表明，由于冷却水温度沿冷却水流动方向的变化，第二流程管束的热负荷明显小于第一流程的，并使蒸汽流动?生侧向偏斜，导致流动与传热特性的恶化。
