A comprehensive shape factor analysis using transportation of MoS2-SiO2/H2O inside an isothermal semi vertical inverted cone with porous boundary

Abstract

Abstract Background and objectives Current article gives a comprehensive shape factor analysis of MoS 2 - SiO 2 water based hybrid nanofluid in a semi vertical inverted porous cone along with the influence of transverse magnetic field, viscous dissipation and thermal radiation. Significances Mathematical investigation is carried out in Cartesian coordinates. Physical flow problem has been tackeled numerically by means of shooting algorithm. Effect of significant emerging parameters is displayed and examined through graphs and tables. Conclusions It is concluded that the presence of magnetic field resist the fluid flow and boundary layer thickness decreases. Fluid decelerates with an increase in λ and this decrease in fluid flow is more in case of nanofluid when compared with hybrid nanofluid. Velocity decreases with an increase in S > 0 . Moreover, it is noticed that the fluid flow decelerates more for SiO 2 /water nanofluid as compare to hybrid nanofluid. For both types of nanofluids temperature distribution upsurges with an increase in Eckert number Ec, volumetric fractions ϕ 1 and ϕ 2 in case of nanofluid and hybrid nanofluid, N as well as λ . Moreover, it is evident that the rise of temperature is significantly more for SiO 2 /water nanofluid. Furthermore, maximum temperature is achieved for blade shaped nanoparticles suspended in SiO 2 /water nanofluid whereas, lowest temperature measurements are observed in case of brick shaped nanoparticles suspended in MoS 2 - SiO 2 /water hybrid nanofluid. Skin friction coefficient and Nusselt number increases with an increase in nanoparticles volumetric fractions ϕ 1 and ϕ 2 for nano as well as hybrid nanofluid, respectively. Moreover, skin friction coefficient and Nusselt number are of maximum magnitude in case of hybrid nanofluid having blade shaped nanoparticles and minimum magnitude is witnessed for brick shaped nano particles suspended in nanofluid.
