【摘要】 本文研究冷却剂流经发热通道时,考虑冷却剂内沿流动方向导热后,冷却剂内温度分布。在稳定导热情况下,利用傅利叶定律和热平衡方程,可得一组三个联立方程式。按热源为常数和热源沿长度按余弦分布二种情况,分别求得联立方程组的解。在不稳定导热情况下,在反应堆丧失冷却剂的事故中冷却剂作等加速度运动流经燃料元件时,推导了在各种情况下冷却剂的温升,进行了若干数值计算并对计算结果进行了讨论。更多还原

【Abstract】 Temperature distribution in the coolant due to heat conduction in the flow di-rection during its flow through a heated channel has been studied.In the case ofsteady heat conduction,by using the Fourier’s law and the heat balance equation,aset of 3 simultaneous equations can be yielded.The solutions for the equations havebeen got separately according to constant heat source distribution and cosine heatsource distribution.In the case of unsteady heat conduction and in the Ioss ofreactor coolant accident,by using the heat source method,temperature rises in thecoolant in various positions have been derived.Some calculations are described andtheir results are discussed.更多还原
