Numerical analysis of a fin-tube plate heat exchanger with winglets
In this presented work, numerical analysis of heat transfer and flow characteristic using longitudinal vortex generators (LVGS) in fin and flat tube heat exchanger has been presented. Conjugate heat transfer 3D numerical model has been developed and successfully carried out. Rectangular winglets …

Effects of flux application and melting parameters in investment casting of pure aluminium by in-situ melting technique
… of the granular aluminium occurs during heating hinders the complete melting of the granules. This research develops a procedure for investment casting of aluminium granules of 99.4% purity by in-situ melting technique. The aluminium granules were filled in ceramic moulds and heated at …

MHD heat and MASS transfer of jet nanofluids flow on the porous wall with chemical reaction
The enhancement of heat and mass transfer of jet flow of nanofluids over a porous wall with chemical reaction effects is numerically studied using different types of nanoparticles such as copper (Cu), alumina ( 2 3 Al O ), and single wall carbon nanotubes (SWCNTs) with water as the base fluid. The …

Unsteady free convection on a horizontal circular cylinder in the presence of heat generation and radiation
… horizontal circular cylinder in the presence of heat generation and radiation is considered in this thesis. The cylinder is fixed and immersed in a Newtonian fluid, while the temperature at the surface is either heated uniformly or oscillated harmonically about the mean temperature, temperature of …

Heat transfer enhancement in a rectangular duct by using winglet and nanofluids
… thermal boundary layer and serves to bring about heat transfer enhancement between the fluid and the fin surfaces. The geometrical configuration considered in this study is representative of a channel with winglets spread over three rows each row 13 a pair of winglets. In this study, three …
