Natural convection flow of a nanofluid in an enclosure under an inclined uniform magnetic field
Tezer, Münevver; Bozkaya, Canan (2016-01-01)
In this study, the natural convection in a square enclosure filled with water-based aluminium oxide (Al2O3) under the influence of an externally applied inclined magnetic field is considered numerically. The flow is steady, two-dimensional and laminar; the nanoparticles and water are assumed to be in thermal equilibrium. The governing equations are solved in terms of stream function-vorticity-temperature using both the dual reciprocity boundary element method and the finite element method to see the influen...
Free convection heat transfer in a stratified medium – cavity problem
Kayserilioğlu, Yavuz Selim; Oskay, Rüknettin; Okutucu Özyurt, Hanife Tuba; Department of Mechanical Engineering (2013)
A numerical study is performed in order to simulate a 2D cavity filled with water having one inlet and one outlet. Relatively warm water is fed to the cavity to charge it while relatively cooler water is drained from the outlet. The top surface of the cavity is exposed to ambient air. Bottom surface is insulated while vertical side surfaces are cooled. Mathematical model comprised of laminar 2D transient flow of an incompressible fluid. Momentum and energy equations are solved simultaneously with Boussinesq...
Natural convection heat transfer from inclined plate-fin heat sinks
Tarı, İlker (2013-01-01)
The steady-state natural convection from heat sinks with parallel arrangement of rectangular cross section vertical plate fins on a vertical base are numerically investigated in order to obtain a validated model that is used for investigating inclined orientations of a heat sink. Taking a previous experimental study as a basis, aluminum heat sinks with two different practical lengths are modeled. The models and the simulation approach are validated by comparing the flat plate heat sink results with the avai...
