Numerical solutions for heat and mass transfer by laminar flow of a Newtonian, viscous, electrically conducting chemically reacting viscous dissipative fluid on a continuously vertical permeable surface in the presence of a heat source, a first – order homogeneous chemical reaction and the mass flux are reported. The plate is assumed to move with a constant velocity in the direction of fluid fl...

The flow problem presented in the paper is boundary-layer flow of nanofluids over a moving surface in the presence of thermal radiation, viscous dissipation and chemical reaction. The plate is assumed to move in the same or opposite direction to the free stream which depends on the sign of the velocity parameter. The partial differential equations appearing in the governing equations are transf...

The prediction of entropy generation with a thermal and exponential space dependent heat source unsteady flow over rotating disk is the artifact paper. For specific physical model, non-Newtonian fluids like Oldroyd-B within EMHD fluid encrypted. Also, mechanism cobalt tantalum nanoparticles in blood employed. proper self-similarity variables are used to convert non-linear PDE system equations i...

This paper investigates the effects of heat and mass transfer on unsteady MHD Nanofluid flow (silver-water) through convergent-divergent channel. The governing equations this study are non-linear partial differential these were reduced to ordinary equations. resulting have been a system first order solved using collocation method via bvp4c in MATLAB. It is found that nanoparticle volume fractio...

The present study elucidates the results on mathematical modeling and numerical for viscous flow demeanor past over plane horizontal surface stretched nonlinearly in two sideways. Furthermore, a comprehensive analysis effects of magnetic field, thermal radiation dissipation are considered observed. Cartesian coordinate system is employed modelling equations. In this research water act as tradit...

The present study investigates the mixed convective MHD flow of Newtonian fluid along an inclined permeable plate which is saturated in porous medium. A non-uniform magnetic field with viscous dissipation and thermal radiation also considered model. Velocity slip conditions are applied at plate. Expressions for skin friction Nusselt number obtained help suitable similarity transformation. Gover...

It is known that almost all 2-qubit gates are universal for quantum computing (Lloyd 1995; Deutsch, Barenco, Eckert 1995). However, an explicit characterization of non-universal 2-qubit gates is not known. We consider a closely related problem of characterizing the set of non-universal 2-qubit Hamiltonians. We call a 2-qubit Hamiltonian n-universal if, when applied on different pairs of qubits,...
