Application of the lattice Boltzmann method for solving the energy equation of a 2-D transient conduction–radiation problem

This article deals with the simultaneous estimation of parameters in a 2-D transient conduction–radiation heat transfer problem. The homogeneous medium is assumed to be absorbing, emitting and scattering. The boundaries of the enclosure are diffuse gray. Three parameters, viz. the scattering albedo, the conduction–radiation parameter and the boundary emissivity, are simultaneously estimated by the inverse method involving the lattice Boltzmann method (LBM) and the finite volume method (FVM) in conjunction with the genetic algorithm (GA). In the direct method, the FVM is used for computing the radiative information while the LBM is used to solve the energy equation. The temperature field obtained in the direct method is used in the inverse method for simultaneous estimation of unknown parameters using the LBM–FVM and the GA. The LBM–FVM–GA combination has been found to accurately predict the unknown parameters.

An inverse analysis of a transient 2-D conduction–radiation problem using the lattice Boltzmann method and the finite volume method coupled with the genetic algorithm

The lattice Boltzmann method (LBM) is used to solve the energy equation of a problem involving conduction and radiation heat transfer with and without heat generation. Both steady and transient situations are considered. To demonstrate that the two different kinds of methods can be coupled, the radiative information for the governing energy equation is computed using the discrete transfer method and the LBM is used to solve the energy equation. For validation purposes, a 1-D planar conducting and radiating medium is considered. Radiatively, the medium is absorbing, emitting, and scattering. Boundaries of the medium are assumed at the specified temperatures. The heat-generation rate is considered uniform and constant throughout the medium. Transient and steady-state medium temperature and heat flux distributions are found for various values of the scattering albedo, emissivity, and conduction-radiation parameter. Results obtained by solving the energy equation using the LBM are compared against th...

Transient Conduction-Radiation Heat Transfer in Participating Media Using the Lattice Boltzmann Method and the Discrete Transfer Method

Numerical simulations have been performed for flow past two equal-sized square cylinders in tandem arrangement subjected to incoming planar shear flow. Effect of L/d ratio and the shear parameter has been studied. The range of L/d ratio (ratio of center-to-center distance (L) to cylinder width (d)) is varied from 2 to 7 and the non-dimensional shear parameter (K) is varied from 0.0 to 0.4 in steps of 0.1. For all the cases the Reynolds number (Re) based on centerline velocity and cylinder width is fixed at 100. The results are compared with that of isolated square cylinder with uniform flow. Strouhal number decreases with increasing shear parameter. There are more than one shedding frequency at high shear parameters and L/d ratios. The mean drag coefficient is decreased with shear parameter and lesser than that of the single cylinder. The root mean square (RMS) value of both lift and drag coefficients is higher for the downstream cylinder for all values of shear parameter. With increasing L/d ratio, for both lift and drag, the RMS value increases and then decreases for upstream cylinder, whereas it continuously increases for the downstream cylinder. The stagnation point is moved towards the top leading edge with increasing shear. The critical L/d ratio, which is defined as the distance between two cylinders, beyond which the vortex shedding from the upstream cylinder occurs, decreases with increasing shear parameter.
