Application of Genetic Algorithms in Nonlinear Heat Conduction Problems

Abstract EN

Genetic algorithms are employed to optimize dimensionless temperature in nonlinear heat conduction problems.

Three common geometries are selected for the analysis and the concept of minimum entropy generation is used to determine the optimum temperatures under the same constraints.

The thermal conductivity is assumed to vary linearly with temperature while internal heat generation is assumed to be uniform.

The dimensionless governing equations are obtained for each selected geometry and the dimensionless temperature distributions are obtained using MATLAB.

It is observed that GA gives the minimum dimensionless temperature in each selected geometry.
