An attempt has been made to study heat and mass transfer effect on MHD mixed convection periodic flow in a rotating vertical porous channel with Hall effect, thermal radiation and chemical reaction. The coupled nonlinear partial differential equation are turned to ordinary differential equation by super imposing a solution with steady and time dependent transient part. Finally, the set of ordinary differential equations are solved with an analytical scheme to meet the inadequacy of boundary condition. The expressions for velocity, temperature and concentration are obtained analytically. The effects of various parameters on the velocity, temperature and concentration are discussed in detail with the aid of graphs.
In this paper, we introduce a fixed point theorem in generalized form for continuous contracting mappings in dislocated quasi-metric space. Our result generalizes and extends the work of Manoj6, Isufati5 and then show that the result of Zeyada4 is special case of our theorem
The heat and mass transfer impacts on a steady 2–dimensional magnetohydrodynamic (MHD) natural,convection boundary layer flow of viscous fluid surrounded by a porous vertical surface with heat source, Ohmic dissipation, chemical reaction and radiation effects are studied. The governing partial differential equations (PDE) are converted into a set of ordinary differential equations (ODE) employing non-dimensional quantities then we solved the ODE employing perturbation method. Most of the studies so far have presented the numerical and semi analytical solutions of flow and heat transfer because of porous vertical surface. Present analysis on analytical solution for the flow velocity and the temperature in the form of a series solution. It was found that increasing the permeability parameter and radiation parameter, the corresponding value of velocityincreases and a reverse trend has seen in magnetic parameter.
In present paper is study of an unsteady free convective viscous incompressible flow past a vertical porous flat plate through porous medium with periodic temperature has been discussed in slip-flow regime. Terms involving viscous dissipation have been retained in the energy equation. The temperature of the plate oscillates in time about a constant mean. The analytical expressions for flow characteristics are obtained for variable suction at the porous plate through porous medium. The effect of various parameters on the transient velocity, transient temperature, the skin-friction and rate of heat transfer are discussed with the help of graphs.
Hyperstructure theory has many applications to several areas of pure and applied sciences. This paper investigates some properties of hyper B -algebras which is a generalization of B -algebras. This paper also introduces the notion of hyper B -ideals, weak hyper B -ideals and strong hyper B -ideals in hyper B - algebras and gives some relations among these hyper B -ideals. Relations between hyper B -ideals and subhyper B -algebras of H is also discussed. Moreover, homomorphism on hyper B -algebra is defined and some related properties are given. Finally, proof of the relationship between the hyper B -algebras and hypergroups is provided.
In this paper, we define pair wise quasi-H-closed modulo an ideal spaces and study some of its properties.
In this paper we use the Hall – Dilworth gluing construction to obtain multiple congruences of a lattice L. For any finite lattice L, ( , ) m n G L B , the gluing of L and n B over F and I, both F and I are isomorphic to 2 C . For any lattice L, the congruences of Gm (L, Bn ) is 2(n1) times the congruences of L where F be the filter of L and I be an ideal of n B and are isomorphic to 2 C . We call ( , ) m n G L B the congruence multiple operator.
