Two-Dimensional Steady Conduction - Gas turbine Engine Technologies (Gas Turbine Blades) A major objective in advancing gas turbine engine technologies is to increase the temperature limit associated with operation of the gas turbine blades. This limit determines the permissible turbine gas inlet temperature, which in turn, strongly influences overall system performance. In addition to fabricating turbine blades from special, high temperature, high-strength super...

This limit determines the permissible turbine gas inlet temperature, which, in turn. strongly influences overall system performance. In addition to fabricating turbine blades from special, high-temperature, high-strength superalloys, it is common to use internal cooling by machining flow channels within the blades and routing air through the channels.

A simplified representation for cooling in very large- scale integration (VLSI) of microelectronics is shown in the sketch below. A silicon chip is mounted in a dielectric substrate, and one surface of the system is convectively cooled, while the reminding surfaces are well insulated from the surrounding. The problem is rendered two dimensional by assuming the system to be very large in the direction perpendicular to the paper. Under steady state (1) and transient (2) operation electronic power dissipation in...

Heat is uniformly generated at the rate of 4 x 105 W/m3 in a wall of thermal conductivity 25 W/m-K and thickness 60 mm. The wall is exposed to convection on both sides, with different heat transfer coefficients and temperatures as shown. There are straight rectangular fins on the right-hand side of the wall, with dimensions as shown (Lf = 16.25 mm) and thermal...

Question 4: (70 Marks) To recover some of the waste heat in the exhaust of a gas turbine, a heat exchanger with unmixed fluids is used. Hot exhaust gases, at Thi-425°C, flow through tubes, and the cold intake air flows across these tubes at Tci= 25°C, and Tco-210°C, The heat exchanger is designed with mass flow rates m-c 10 kg/s, heat transfer coefficients...
