摘要
以室温下的水为介质,以涡量 流函数为理论基础,运用代数变换法生成适体坐标,通过有限差分对波纹板板内流场进行了数值模拟;并以Re=500为例,求出其板内流体的速度场和压力场,进而对同一周期内和不同周期的速度场和压力场进行分析,给出了速度和压力分布变化曲线图,得出了不同雷诺数下流动阻力损失变化曲线与阻力关联式,为波纹板的强化传热研究提供了有利的参考。
Based on the Stream function-Vorticity method, the flow characteristics in wavy plates, with water at ambient normal temperature as the medium, was simulated by finite difference method in the body-fitted coordinates formed by algebraic transformation. Taking Re=500 as an example, the velocity and pressure field were computed and analyzed for the same periodical and different periodical passages. At the same time, the distribution curves of the velocity and pressure were given. The correlation of flow resistance was obtained and its variation curve was drawn at different Reynolds number. This provides advantageous reference to the research on heat transfer enhancement of wavy plates.
