Abstract: In this work, equations that govern axisymmetric incompressible turbulent flow for heat transfer calculations are derived assuming constant thermo-physical properties and a specific nondimensionalization scheme.Vector algebra is used for expanding vector form of governing equations in cylindrical coordinate system.Emphasis is on the derivatives of unit vectors according to azimuthal direction.Reynolds decomposition is used for separating time averaged terms and Reynolds Stress terms.Standard k-ϵ turbulence model is selected for solving closure problem due to the Reynolds stresses.Organization of the governing equations after model inputs is done explicitly.Also, parameters that constitute nondimensionalization scheme are given.Evaluations of the complete process are given.Two major aims of the work are presenting necessary equations explicitly and revealing some key steps for reorganization of the equations.It is also aimed to present novel illustrations in order to contribute comprehension of the concepts.
