Effects of radiation, joule heating and viscous dissipation on MHD Marangoni convection over a flat surface with suction and injection
(International Digital Organization for Scientific Information (IDOSI) Publications, 2013)In this paper, we studied the effects of thermal radiation, Joule heating and viscous dissipation on magnetohydrodynamics (MHD) Marangoni convection boundary layer over a flat surface. We also investigated the influence ... -
Enhancement of algorithm and investigation of heat transfer through fins
(Praise Worthy Prize S.r.l., 2013-09)Finite Element Method (FEM) and Differential Quadrature Method (DQM) are two very important numerical solution techniques to solve engineering and physical science problems. Usually elements are sub-divided uniformly in ... -
Unsteady flow due to a contracting cylinder in a nanofluid using Buongiorno’s model
(Elsevier, 2014-01)The unsteady flow and heat transfer of a nanofluid over a contracting cylinder is studied. Using a similarity transformation, the unsteady Navier–Stokes equations are transformed into a system of ordinary differential ... -
Analytical and numerical solutions of fuzzy differential equations
(Elsevier Inc., 2013-07)In this paper, we study analytical and numerical solutions of fuzzy differential equations based on the extension principle. For linear fuzzy differential equations, we state some results on the behaviour of the solutions ... -
Solving fuzzy fractional differential equations using Zadeh's extension principle
(Hindawi Publishing Corporation, 2013)We study a fuzzy fractional differential equation (FFDE) and present its solution using Zadeh's extension principle. The proposed study extends the case of fuzzy differential equations of integer order. We also propose a ... -
Further improvement in the variational many-body wave functions for light nuclei
(American Physical Society, 2012-09)An improved variational ansatz is proposed and implemented for variational many-body wave functions for light nuclei with nucleons interacting through Argonne (AV 18) and Urbana IX (UIX) three-nucleon interactions. The new ... -
