Abstract

As a basic problem in many engineering applications transition from laminar to turbulence still remains a difficult problem in computational fluid dynamics CFD A numerical study of one transitional flow in twodimensional is conducted by Reynolds averaged numerical simulation RANS in this paper Turbulence model plays a significant role in the complex flows’ simulation and four advanced turbulence models are evaluated Numerical solution of frictional resistance coefficient is compared with the measured one in the transitional zone which indicates that Wilcox 2006 kω model with correction is the best candidate Comparisons of numerical and analytical solutions for dimensionless velocity show that averaged streamwise dimensionless velocity profiles correct the shape rapidly in transitional region Furthermore turbulence quantities such as turbulence kinetic energy eddy viscosity and Reynolds stress are also studied which are helpful to learn the transition’s behaviorZhi Zong is presently a professor and dean at School of Naval Architecture Dalian University of Technology He has been the principal investigator of a large variety of funded research work regarding the design and optimization of conventional and unconventional vessels His research interests include hydrodynamics underwater explosion and numerical methods in CFD etc His activities are documented by an extensive publication record of scientific papers books technical reports and papers at international conferences over 200 publications and two English monographs He is the editorial advisory board member of several academic journals including Journal of Hydrodynamics Journal of Marine Science and Application and so on
