Heat exchangers (HEs) are often modeled using pinch point temperature difference (ΔT<sub>pinch</sub>) methods when
optimizing systems with HEs. However, even small inaccuracies in model predictions of HEs will introduce
numerical noise that can cause optimization algorithms to fail. A recent study of single HEs suggests that highorder interpolation methods can compute ΔT<sub>pinch</sub> much faster ...
