Mixed convection of Cu-Water nanofluid is studied numerically in a shallow inclined enclosure by applying lattice Boltzmann method. The D2Q9 lattice and internal energy distribution function based on the BGK collision operator are used in order to develop the thermal flow field. The enclosure's hot lid has the constant velocity of U0 while its cold lower wall has no motion. Moreover, sidewalls ...

an attempt is made for the first time to solve the quadratic and cubic model of magneto hydrodynamic poiseuille flow of phan-thein-tanner (ptt). series solution of magneto hydrodynamic (mhd) flow is developed by using homotopy perturbation method (hpm). results are presented graphically and the effects of non-dimensional parameters on the flow field are analyzed. the results obtained reveals ma...

New two-dimensional, high-resolution calculations of a core collapse supernova in a 15 M ⊙ blue supergiant are presented, which cover the entire evolution from shock revival until the first few hours of the explosion. Explosive nucleosynthesis, its dependence upon convective mixing during the first second of the evolution and the growth of Rayleigh-Taylor instabilities at the composition interf...

We performed 3D hydrodynamic simulations of the inner $\approx 50\%$ radial extent a $25\ \mathrm{M_\odot}$ star in early phase main sequence and investigate core convection internal gravity waves core-envelope boundary region. Simulations for different grid resolutions driving luminosities establish scaling relations to constrain models mixing 1D applications. As previous works, turbulent mass...

The phenomena of magneto-hydrodynamic natural convection in a two-dimensional semicircular top enclosure with triangular obstacle the rectangular cavity were studied numerically. governing differential equations are solved by using most important method which is finite element (weighted-residual method). wall placed at cold Tc and bottom heated Th. Here sidewalls assumed adiabatic. Also all occ...

in the procedure of designing an underwater vehicle or robot, its maneuverability and controllability must be simulated and tested, before the product is finalized for manufacturing. since the hydrodynamic forces and moments highly affect the dynamic and maneuverability of the system, they must be estimated with a reasonable accuracy. in this study, hydrodynamic coefficients of an autonomous un...

Methods Clinical Records of 17 children (16 girls and 1 boy) were retrospectively analyzed over a period of 24 months (Mar 2012 to Mar 2014). All children satisfied the criteria for precocity based on clinical features, radiological assessment and GnRHa stimulation test. All 16 girls had idiopathic precocious puberty and the only boy had hypothalamic hamartoma. The mean age of presentation was ...

A computational model is developed to simulate the hydrodynamic and heat transfer behavior of a melting cylindrical solid particle in plane Poiseuille flow between horizontal parallel plates. The two-dimensional transient conservation equations for mass, momentum, energy are solved using finite-volume scheme implemented on deforming mesh, accounting rotation non-uniform particle. An arbitrary L...

Abstract Simulating deep solar convection and its coupled mean-field motions is a formidable challenge where few observational results constrain models that suffer from the nonphysical influence of grid resolution. We present hydrodynamic global implicit large-eddy simulations performed with EULAG-MHD code, we explore effects resolution on properties rotating nonrotating convection. The results...

The numerical study of thin film type condensation in forced convection a saturated pure vapor an inclined wall covered with porous material is presented. generalized Darcy-Brinkman-Forchheimer (DBF) model used to describe the flow medium while classical boundary layer equations have been exploited case liquid. dimensionless are solved by implicit finite difference method and iterative Gauss-Se...
