News Update on MHD Flow Research: Dec – 2019

MHD flow of a viscoelastic fluid past a stretching surface

The flow of a viscoelastic fluid past a stretching sheet inside the presence of a transverse magnetic area is taken into consideration. An genuine analytical solution of the governing non-linear boundary layer equation is received, showing that an outside magnetic discipline has the same effect at the go with the flow because the viscoelasticity.

Effect of thermal radiation on MHD flow

An analysis of the regular MHD asymmetric float of an electrically undertaking fluid past a semi-endless desk bound plate is taken into consideration within the presence of radiation. Numerical solutions for the temperature subject had been derived and the impact of the radiation parameter is mentioned. [2]

Entropy generation in steady MHD flow due to a rotating porous disk in a nanofluid

We remember the analysis of the second one law of thermodynamics carried out to an electrically conducting incompressible nanofluid fluid flowing over a porous rotating disk within the presence of an externally implemented uniform vertical magnetic subject. This have a look at has applications in rotating magneto-hydrodynamic (MHD) electricity generators for brand spanking new space structures and additionally thermal conversion mechanisms for nuclear propulsion space vehicles. Von Karman modifications are employed to transform the governing equations into a gadget of nonlinear normal differential equations. The entropy technology equation is derived as a feature of speed and temperature gradient. This equation is non-dimensionalized the use of geometrical and physical waft area-based parameters. [3]

MHD Flow of Sodium Alginate-Based Casson Type Nanofluid Passing Through A Porous Medium With Newtonian Heating

Casson nanofluid, unsteady glide over an isothermal vertical plate with Newtonian heating (NH) is investigated. Sodium alginate (base fluid)is taken as counter instance of Casson fluid. MHD and porosity outcomes are considered. Effects of thermal radiation along with heat generation are examined. Sodium alginate with Silver, Titanium oxide, Copper and Aluminum oxide are added as nano particles. Initial value trouble with bodily boundary situation is solved by means of the use of Laplace transform technique. Exact consequences are obtained for temperature and pace fields. Skin-friction and Nusselt wide variety are calculated. The received results are analyzed graphically for emerging glide parameters and mentioned. [4]

Effect of Electric Field on MHD Flow and Heat Transfer Characteristics of Williamson Nanofluid over a Heated Surface with Variable Thickness. OHAM Solution

The magneto-hydrodynamic flow with warmth and mass transfer of Williamson nanofluid over a heated surface with a variable thickness under the impact of an electric place is tested. It is notion that the sheet is non-flat. The bobbing up glide governing equations are simplified under the equal vintage boundary layer suppositions. The answer of particularly nonlinear converted simultaneous differential equations is computed through an green analytic technique known as satisfactory homotopy asymptotic technique (OHAM). Consequently, the outcomes of the governing parameters of the velocity, temperature and attention profiles are provided graphically and noted. It is seen that the impact of an electric place has an immediate impact on the conduct of the magnetic challenge within the tempo profile and an increment of Biot range  implies stronger convection on the floor. Comparison of outcomes has been made with the present literature, and a brilliant covenant has been determined. [5]
