Polytropic work equation
WebBecause polytropic processes are general representations of thermodynamic pro-cesses, any quantities we calculate for a polytropic process will be a general equation for that … WebThermoelectric generators (TEGs) offer an attractive power generation option. They have no moving parts, are robust and emit no pollutants. The current work explores the integration of high temperature TEGs in gas turbine combustors. The latter have a thermal shield at their inner surface to protect them against high temperatures. This is supplemented by …
