In this paper, the proposed novel technique using computational fluid dynamics (CFD) approach to design control systems is validated experimentally for a chip cooling device. Both experimental approach and CFD simulations are employed to extract the dynamic characteristics from the non-linear chip cooling system around a specific operating point, which are then used to construct the linear dynamic model for the chip cooling system. The linear dynamic model has two inputs, the heat load generated by the chip and the cooling fan voltage. The output is the temperature of the case housing the chip. The results from the linear dynamic model obtained by the CFD approach are compared with those obtained experimentally under the same dynamic conditions to validate the feasibility of using the CFD approach to design a control system for a thermal-fluid system.
