A Pseudospectral Analysis of Laminar Natural Convection Flow and Heat Transfer Between Two Inclined Parallel Plates

A fast model for computing infrared atmospheric background effects Sivaslıgil, Mustafa; Esendemir, Akif; Department of Physics (2006) The infrared atmospheric background modeling can be considered as one of the important key factor to develop a successful target detection technique. During the infrared atmospheric background modeling, defining the input parameters of the atmospheric profile are very important for the calculations of the absorption, emission and scattering effects of the atmosphere. The main objective of this thesis is to find the answer for the question أis it possible to determine the أeffectiveؤ height range for the sea...
Investigation of radiative heat transfer in freeboard of a 0.3 MWt AFBC test rig Kozan, M; Selçuk, Nevin (2000-01-01) Based on the analysis of measured data on flow rates, concentrations and temperatures taken during steady state operation of a lignite-fired 0.3 MWt Atmospheric Fluidized Bed Combustor (AFBC) test rig, radiative exchange in freeboard of the combustor was modeled by using a well-stirred enclosure model in conjunction with Radiosity-Irradiation Method (RIM). Radiative properties of the particle laden combustion gases were calculated by assuming grey radiation behaviour for both particles and gas, and using Le...
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...
A method to predict temperature derivatives of the bulk modulus: A case study for HfB2 Özkan, Hüsnü; Delice, Serdar; Hasanlı, Nızamı (2022-08-01) © 2022 IOP Publishing Ltd.Hafnium diboride (HfB2) is an ultra-high temperature ceramic that has attracted increased attention for its fascinating properties. In this study, temperature derivatives of the bulk modulus of HfB2 were calculated from room temperature up to 2273 K by using the relevant theoretical thermodynamic equations for the bulk modulus. The equations used involve the parameters as the enthalpy, thermal expansion and heat capacity in addition to the Anderson Grüneisen parameter. The calculat...
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 ...
