本文研究了热流体进口温度阶跃、斜坡和指数扰动下，两种流体不混合且壁容有限的错流换热器的瞬态温度响应。研究了分离片中二维纵向导热和流体中轴向弥散对瞬态响应的影响。对流体中存在轴向弥散时的热传导进行了详细的分析
Transient temperature response of the crossflow heat exchangers with finite wall capacitance and both fluids unmixed is investigated numerically for step, ramp and exponential perturbations provided in hot fluid inlet temperature. Effect of two-dimensional longitudinal conduction in separating sheet and axial dispersion in fluids on the transient response has been investigated. Conductive heat transport due to presence of axial dispersion in fluids have been analyzed in detail
