Our research deals with synthesis tasks for fluid systems. A typical job is to decide a system topology considering investment costs, operational costs and system control which again depends on various load profiles. We present a stationary optimization model for a booster station. In principle, such a fluid system consists of a flow problem with some non-linear constraints that are linearized. We also aim at an automatic conversion from Engineer’s language into this MIP. We present the basics of such a domain specific language which enables us to utilize classic compiler techniques.
