Inverse boundary design of two-dimensional irregular enclosures using micro-genetic algorithm

The goal of the inverse analysis is to find a set of heaters over some parts of boundary, called the heater surface, to satisfy the desired heat flux profile over the design surface. Micro-genetic algorithm is employed to inverse design of a radiant enclosure with absorbing-emitting medium. The direct problem of radiative heat transfer is solved by the discrete transfer method. The inverse problem is solved through the minimization of an appropriate objective function using the micro-genetic algorithm. A smoothing criterion is used to achieve a smooth distribution of heaters over the heater surface. The desired heat fluxes over the design surface are well recovered by employing a smooth distribution of heaters over the heater surface. The ability of the method to solve the inverse problem in complex geometries is investigated by a complex problem. Key-Words: Micro-genetic-Radiant enclosure-Discrete transfer`
