عنوان المقالة: Investigation of fluid field analysis, characteristics of pressure drop and improvement of heat transfer in three-dimensional circular corrugated pipes
In this investigation, the computational technique is carried out to study flow behaviour analysis, pressure drop characteristic and enhancement of heat transfer in three-dimensions smooth pipe and circular corrugated tube (circular sectional area rings are inserted around the tube). Various rings are considered as 0.375, 0.5 and 1 mm. Water is chosen as working fluid and at the tube external surface uniform heat flux is applied. Numerical simulation is performed computational fluid dynamics method at range of Reynolds number from 1500 to 24,000. To calculate the process of governing equations and energy analysis equations in numerical calculations the pressure-based solver double precession is used. Numerical simulation outcomes are validated with available experimental results. Also, the results shown a good agreement between them. Result indicated that the dynamic pressure profile and velocity profile
