Very low-pressure-ratio gas turbines can obtain very high theoretical efficiencies if they are operated in a regenerative cycle with very effective (0.95) heat exchangers. A 50,000-hp engine operates at a pressure ratio of 3:1 and has a turbine inlet temperature of 1,5000E Design a 95 percent effective regenerator for this application where the hot-side surface […]

Design a regenerator for a gas turbine engine. The engine is to deliver 50,000 hp with a compression ratio of 4:1 and a turbine inlet temperature of2,0000E The regenerator should have an effectiveness of 0.85 and pressure drops not to exceed 0.5 psi. The pressure drop of the combustor is 1.0 psi.

Calculate the overall heat transfer coefficient and the duty (rating) of heat flow from the hot gases to the cold air in the cross-flow tube bank of the heat exchanger sketched in Pig. P3-16. The following operating conditions are given: air flow rate = 3,000 lbm/hr hot-gas flow rate = 5,000 lbm/hr hot-gas inlet temperature

Gas turbines often use regenerative cycles to improve overall operating efficiency. The schematic shown in Figure P3-18 is an example of a gas turbine engine with a regenerator. Extensive cycle analyzes have established that for optimum cycle operating efficiency, the following specifications are required fot the regenerator. Using heat transfer surfaces available in the book,

In an industrial plant a shell-and-tube heat exchanger is heating water initially at 120°F by means of steam condensing at 280°F on the outside of the tubes. The heat exchanger has 50 steel tubes (ID = 0.052 ft and OD = 0.070 ft) in a tube bundle which is 10 ft long. The water flows
