Numerical Modeling of Turbulent Heat Exchange in the Combustion Chambers of Gas‐Turbine Plants with the Use of the Fluent Package

The processes of combustion in the combustion chamber of a gasturbine plant are numerically modeled using the Fluent CFD package. A detailed comparison of the obtained calculation results and the data of bench tests has been made.     

Numerical analysis of aerodynamics and hydraulic loss in the GTÉ-150 combustion chamber of gas-turbine power plant with the use of the fluent suite

The aerodynamic structure of the flow in the combustion chamber of the GTé-150 gas-turbine power plant has been simulated numerically by means of the FLUENT suite CFD. The influence of the processes of turbulent heat and mass transfer (and combustion) on the hydraulic loss in the combustion chamber has been investigated. Detailed comparison of the calculated and experimental data on the total pressure loss both n the combustion chamber proper and in its individual units has been carried out. __________ Translated from Inzhenerno-Fizicheskii Zhurnal, Vol. 79, No. 4, pp. 45–49, July–August, 2006.     

Skewed CMOS: noise-tolerant high-performance low-power static circuit family

In this paper, we present a noise-tolerant high-performance static circuit family suitable for low-voltage operation called skewed logic. Skewed logic circuits in comparison with Domino logic have better scalability and are more suitable for low voltage applications because of better noise margins. Skewed logic and its variations have been compared with Domino logic in terms of delay, power, and dynamic noise margin. A design methodology for skewed CMOS pipelined circuits has been developed. To demonstrate the applicability of the proposed logic style, 0.35 /spl mu/m 5.56 ns CMOS 16/spl times/16 bit multipliers have been designed using skewed logic circuits and fabricated through MOSIS. Measurement results show that the multiplier only consumed a power of 195 mW due to its low clock load.
