Iceformation phenomena can be observed in many natural and technical processes. A naturally grown ice layer aspires in steady state to a minimum of energy dissipation. Driven by this goal, this phenomena can be used to optimize complex geometric configurations in a natural manner. But since this state of minimum energy dissipation is seldom the desired goal function in technical applications, this natural experimental optimization method is combined with a subsequent classical numerical optimization using evolutionary algorithms at the example of an internal cooling channel of a gas turbine blade.
