建立了一种百叶窗翅片的二维数学模型，采用SIMPLER算法，对空气流经翅片的传热和流动特性进行了数值模拟计算，获得了百叶窗翅片的温度场，速度场和流线图。对不同百叶窗倾角和不同雷诺数进行了数值模拟，结果揭示了阻力系数和Nu数的变化规律。在此基础上，采用场协同原理分析了温度梯度与速度矢量的夹角对百叶窗翅片换热的影响-A two dimensional numerical model is established for a type of louvered fin, the temperature

PMSM Electrical Parameters Measurement-The vector control, also known as the field-oriented control (FOC), of a permanent magnet synchronous motor (PMSM) is the algorithm often used in today’s advanced motor control drives. Such advanced moto
