تحليل رقمي ثلاثي الابعاد باستخدام تقنية CFD لمبادل حراري حلزوني صفائحي مع مقارنة لحالتي الجريان الصفحي والمضطرب

In this research, we have used Computational Fluid Dynamics (CFD) to perform a 3D Numerical Analysis 3D in order to define heat transfer properties for a Spiral Plate Heat Exchanger by changing flow properties in cases of the turbulent flow and laminare flow by using ANSYS FLUENT 12.1.2 . And, a comparsion has been made between the two cases in terms of static pressure, dynamic pressure, domain distribution of static temperature, total temperature for cold fluid and hot fluid in addition to hat plate at speed of certain working conditions, as well as defining the effect of tempurature at inlet and outlet of Heat Exchangers to both fluids on thermal capacity and thermal yield according to nature flow (turbulent flow, laminare flow), on parpose of finding the best values for parameters wich work to improve the efficiency of Plate Spiral Heat Exchangers.
