In this paper, we discuss the use of a sensitivity equation method to compute,t-ri vat i ves for optimization based design algorithms. The problem of designing an optimal fore!bod y simulator is used to motivate the algorithm and to illustrate the basic ideas. Finally. wke indicate how an existing CFD code can be modified to compute sensitivities and a nmnwrical example is presented. By....... D{ _ b!tK-J'')
