Computations, based on finite volume method, were carried out by utilizing the standard k-<img title="\varepsilon" src="https://latex.codecogs.com/gif.latex?\varepsilon"> model and the Algebraic Reynolds stress model (ASM) for the closure of the second-order correlation moment in the time averaged governing equations. It is observed that the Algebraic Reynolds stress model (ASM) performs better than the k-<img title="\varepsilon" src="https://latex.codecogs.com/gif.latex?\varepsilon"> model in predicting the axial and tangential velocity profiles. In addition, computations using different numerical differencing schemes found that the use of upwind and hybrid schemes leads to slightly better results than that of QUICK and SOU schemes.</p>}, number={2}, journal={Journal of Research and Applications in Mechanical Engineering}, author={Sripattanapipat, S.}, year={2018}, month={Oct.}, pages={111–121} }
