Three dimensional laminar natural convection flow of and heat transfer in incompressible air between two inclined parallel plates are analyzed with the Boussinesq approximation by using spectral methods. The plates are assumed to be infinitely long in streamwise and spanwise directions. For these directions, periodic boundary conditions are used and for the normal direction constant wall temperature and no slip boundary conditions are used. Unsteady Navier-Stokes and energy equations are solved using a pseudospectral C code in order to obtain velocity and temperature profiles inside the channel. Fourier series are used to expand the variables in x and z directions, while Chebyshev polynomials are used to expand the variables in y direction. By using the temperature distribution between the plates, local and average Nusselt numbers (Nu) are calculated. Nu values are correlated with ?,which is the inclination angle, and with Racos? to compare the results with the literature. Additionally, non-dimensional velocity values and streamlines of the fluid are presented with proper plots.

A numerical study of single-phase convective heat transfer in microtubes for slip flow Sun, Wei; Kakac, Sadik; Yazicioglu, Almila G. (2007-11-01) The steady-state convective heat transfer for laminar, two-dimensional, incompressible rarefied gas flow in the thermal entrance region of a tube under constant wall temperature, constant wall heat flux, and linear variation of wall temperature boundary conditions are investigated by the finite-volume finite difference scheme with slip flow and temperature jump conditions. Viscous heating is also included, and the solutions are compared with theoretical results where viscous heating has been neglected. For ...
A three dimensional numerical study on natural convection heat transfer from short horizontal rectangular fin array Mobedi, M; Yüncü, Hafit (2003-05-01) Steady state natural convection heat transfer in a longitudinally short rectangular fin array on a horizontal base is numerically investigated. The problem is three dimensional laminar natural convection heat transfer with open boundaries. A finite difference code based on vorticity-vector potential approach is developed to solve the governing equations. The steady behaviour of the flow and temperature distributions is obtained from the solution of transient form of the governing equations. Results are comp...
A CSCM approximation of steady MHD flow and heat transfer between parallel plates with hydrodynamic slip and convective boundary conditions Tezer, Münevver; Türk, Önder (null; 2019-10-04) The steady magnetohydrodynamic (MHD) flow together with its heat transfer between parallel plates is considered in which the electrically conducting fluid has temperature dependent properties such as viscosity, thermal and electrical conductivity. The fluid is driven by a constant pressure gradient, and a uniform external transverse magnetic field is applied perpendicular to the plates. The effects of viscous and Joule dissipations are considered in the energy equation, and the fluid is assumed to be slippi...

A numerical study on magneto-hydrodynamic mixed convection flow Bozkaya, Canan (2014-01-01) This paper, describes a study conducted to numerically investigate the two-dimensional, steady, laminar, magneto-hydrodynamic mixed convection flow and heat transfer characteristics in a lid-driven enclosure beneath an externally applied magnetic field. A solid square block is placed inside the cavity. The governing equations in the form of a stream function-vorticity-temperature formulation are solved numerically using the dual reciprocity boundary element method with constant elements. Treatment of nonlin...
