Mixed convective cilia triggered stream of magneto ternary nanofluid through elastic electroosmotic pump: A comparative entropic analysis

Abstract

Integration of ternary nanofluid with micro-pump heat sink is considered to be the incredible heat exclusion from thermal pumps/channels. The present work intends to present a theoretical thermal analysis of mixed convective transport of radiated magneto ternary fluid through an electroosmotic pump. To achieve efficient mixing and effective pumping, the inner surface of pump is embedded with bio-mimetic cilia. The cilia beat in synchronization to commence a train of metachronal waves along the elastic surface of micropump. The blood based ternary nanofluid is considered as working fluid in the pump by mixing trihybrid nanoparticles of TiO2, SiO2 and Al2O3 in blood. The mixed and forced convection situations are set with the help appropriate governing equations and solved analytically. A comparative exergy analysis between ternary, binary, unary nanofluid and conventional blood is also presented. In comparison the ternary hybrid nanofluid is observed be more thermally efficient then the unary and binary nanofluids and has significant ability to minimize heat losses. The ternary nanofluid shows an effective role in augmenting the heat transfer rate by lifting the rate up to 18.03% at smaller Hartmann number specifically at 0.5. It is further reported that thick EDL and high values of the Hartmann number dampens down the TiO2-SiO2-Al2O3/blood temperature.
