A Review on Heat Transfer and Fluid Flow within U-pipe and Bend Pipe

Abstract

Abstract-This paper focuses on extensive literature review in the field of heat transfer and fluid flow within the U pipe or bends Pipe. Several researchers have examined the fluid flow characteristics experimentally as well as computationally. Pipes are extensive been used in various application from day to day life to various engineering marvels. Within the pipe when fluid flows, due to friction various losses takes place which affects the hydrodynamics as well as thermo hydrodynamics performance. At turbulent flow, the flow within these bend pipes have high significance in terms of secondary flow or flow separation. Researcher examined these flow characteristics and developed various empirical correlations which are particularly been used in exploring other engineering application.
