In a turbulent supercritical fluid flow, the variations of the fluid properties are significant near the pseudo-critical temperature. Such dramatic variation of the fluid properties makes the convection heat transfer to a supercritical fluid a complex phenomenon. A number of studies in recent years have used the available CFD codes to predict heat transfer coefficients. In this study, the upward turbulent flow of supercritical water in a pipe has been examined by means of the FLUENT software. To model the turbulence, RSM and RNG k-e models are employed. The results associated with RSM model demonstrate a better agreement with experiments. The basic characteristics of convection heat transfer in a supercritical fluid medium, including the effects of pressure and heat flux for example, are predicted satisfactorily. However, the inadequacy of existing turbulence modeling seems to be apparent. 2012-07-18T02:59:30Z 2012-07-18T02:59:30Z 2012-02-27 Working Paper http://hdl.handle.net/123456789/20384 en Proceedings of the International Conference on Applications and Design in Mechanical Engineering 2012 (ICADME 2012) Universiti Malaysia Perlis (UniMAP) Pusat Pengajian Kejuruteraan Mekatronik
