Thermal calculation of recuperator. The differential equation for the relationship between medium temperature and the size heat transfer surface. Solving equations for various cases boundary conditions. 3. Dependence of temperature difference between the hot and cold streams on the size of the heat transfer surface. Calculation of the mean temperature difference. 4. Heat transfer coefficient for the ceramic and metal recuperators. Influence of heat transfer coefficients on the overall heat transfer coefficient 5. Heat rate of recuperator. Temperature heat transfer surfaces in the consideration or neglecting the thermal resistence of heat transfer surfaces, a criteria expression. 6. The definition of heat exchanger effectiveness. Determination of heat exchanger effectiveness for the parallel and counterflow cases for different ratios between total heat capacities. 7. Hydraulic calculation. Pressure loss by friction, local, geometric. Pressure losses resulting from non-isothermal flow mediums. 8. Types of metal, ceramic and plastic heat exchangers.
