WebThe most common type of thermal-stress analysis is one in which the temperature field does not depend on the stress field. In such cases temperature is calculated in an uncoupled heat transfer analysis (“Uncoupled heat transfer analysis,” Section 6.5.2) or in a coupled thermal-electrical analysis (“Coupled thermal-electrical analysis,” Section 6.6.2). WebUse of passive heat transport systems in renewable energy eliminates operator and external power requirements, thereby reducing the cost. Hence, a horizontal heater and horizontal cooler rectangular natural circulation loop (NCL) of low L/D (110) and aspect ratio (0.54) is coupled to a parabolic trough in the present work.
