Title: Large Eddy Simulation of Flow and Heat Transfer in a Pipe With Corrugated Walls
Authors: Lindroth, Daniel
Abstract: Large Eddy Simulation of the flow and heat transfer on the inside of a pipe with corrugated walls has been conducted on a fluid with Prandtl number Pr = 3.5, at Reynolds number Re_d = 10^4 . The system’s friction coefficient C_f , dimensionless pressure drop and Nusselt number Nu based on the simulation are presented and compared to a straight pipe. Some basic properties connected to the characteristics of the flow and thermal properties of the simulation are discussed. It is hypothised that the local loss in performance is related to the accumulation of the periodic wall temperature and that the increase in performance is related to the decreasing radius of the corrugated pipe.
