| Popis: | The development of advanced-performance thermal frameworks for increased heat transport has proved to be of remarkable interest these days. Therefore, present attempt is intended to deal with entropy generation and heat transfer analysis for the peristaltic flow of an electrically conducting silver-water nanoliquid through a symmetric channel. System is supposed to be affected by an external magnetic field and electrical conductivity of nanofluid is considered to vary with temperature. Mixed convection, joule heating aspects along with thermal and velocity slip conditions are considered in analysis. Two phase model of nanofluids is adopted. Mathematical modeling for entropy generation is carried out via second law of thermodynamics. Making use of numerical solver NDSolve, graphical analysis for entropy generation, heat transfer, Bejan number and velocity is presented. Results reveal that by enhancing electrical conductivity parameter entropy generation increases. It is further deduced that entropy generation can be minimized by addition of silver nanoparticles. Bejan number increases by increasing Grashoff number. For large values of Hartman number temperature increases. Temperature of nanofluid increases by enhancing thermal slip parameter. Increase in Grashoff number provides better rate of heat transport at the boundary. Moreover, velocity decreases by enhancing velocity slip parameter. |
