Dynamic behaviour of heat exchanger
WebTo minimize energy losses, it is important to have optimal systems, where both static and dynamic properties of the components are adjusted to each other. Typically the static behavior of a heat exchanger is well-known, while the dynamical behavior of a system of connected valves, pumps and heat exchangersis less known. Webof the dynamic behaviour of heat exchangers can be found in the book of Roetzel The theoretical fundamentals, mathematical modeling and numerical simulations …
