Abstract

The forced flow behaviour for a grooved geometry attached with a nozzle has been analysed in the current study. A geometry with triangular grooves on either walls of the surface has been attached with nozzle having different angles of convergence. The angle of convergence has been restricted to a range of 10^o to 90^o. These geometries with the modifications in each of the case has been examined for the heat swapping contours using the ANSYS – FLUENT software. The analysis depicted the results accordingly by the applied conditions using the software conceptions. These conception generated results displayed the geometry with 45^o convergence angle of the nozzle as the optimum one as it has depicted the maximum deviation in terms of the heat swapping. This intermediate geometry between the 40^o and 50^o has been considered as the best one, i.e,. the mean geometry for both. The generated software results has been compared with the regression data using the equations generated. These comparisons depicted the maximum accuracy thereby declaring that both the data are in good correlation with each other. These comparisons can be applied to larger models with further modifications.
