Turbulent temperature field in a channel with wall injection has been investigated using dynamic mixed<br/> model(DMM). This flow is pertinent to internal flows inside the hybrid rocket motors. In general, the results<br/> obtained with DMM are in better agreement with DNS results compared to those of dynamic Smagorinsky<br/> model(DSM). Such favorable features of DMM are attributed to the fact that it explicitly calculates the<br/> modified Leonard stress term which takes care of the local interaction between resolved and SGS stresses and<br/> only models the remaining cross and SGS Reynolds stress terms.
