Abstract
The solution of heat exchanger models is usually influenced by different parameters related to fluid properties, geometry and flow conditions. This implies that several simulations are usually required for design and optimization purposes. In this work, a sensitivity analysis using perturbative methods is presented as an alternative for reducing the computational cost of studying the sensitivity of the solution to different parameters. The method is based on the computation of the adjoint problem, and thus only one extra simulation is required for studying the sensitivity of an integral response, regardless of the number of parameters. Both the direct and the adjoint problem were solved using a least squares formulation.
