A direct-transfer intercooler for a gas turbine is to be designed using either surface 8.0-iT or surface 9.29-0.737-SR. The requirements are: The heat exchanger can be the necessary width, but the air inlet side must be 1.5 ft X 4 ft. Water flows through the tubes. Select the better surface based on economy of operation […]

The cross-flow heat exchanger illustrated in Fig. P3-9 uses surface CP-7.0-5/8J shown in Pig: 3-20(i). A light oil at 120°F flows through the tubes, and air at 1000P and 14.7 psia flows over the tubes. The flow rate of the air is 34.0 lbm/s, and the flow rate of the oil is 42.5 Ibm/a The

A gas turbine regenerator used to preheat combustion air is to be designed. An airstream from the compressor is to be heated by the gas discharge (combustion products) from the turbine. The characteristics are as follows.Determine the dimensions of the regenerator subject to the constraints given.

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.

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

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
