A set of enhancements to the ASHRAE Handbook [1] are presented to demonstrate the effectiveness of multimedia and advanced presentation techniques such as 3D computer graphics, visualization and animation techniques. These results can also serve as a model and guide for the broader use of these techniques in other ASHRAE publications. 1 General Introduction to Project In this paper, we present ...

A comprehensive cost correlation analysis was conducted based on available correlations, and new equipment models were proposed QUE$TOR modeling. Cost correlations for various types of such as pumps, compressors, heat exchangers, air coolers, pressure vessels generated the basis extracted data. The derived robust multivariable regression with aim minimizing residuals by using genetic algorithm....

The aim of this publication was to investigate the effects blade count a high-pressure centrifugal compressor’s impeller has on performance DGEN 380 turbine engine at take-off. study began with development zero-dimensional thermo-fluid model engine. matched experimental data from WESTT CS/BV virtual test bench for baseline and then implemented analyse behaviour alternative counts. corresponding...

For higher order multiplications, a huge number of adders or compressors are to be used to perform the partial product addition. We have reduced the number of adders by introducing special kind of adders that are capable to add five/six/seven bits per decade. These adders are called compressors. Binary counter property has been merged with the compressor property to develop high order compresso...

Labyrinth seals are widely used in centrifugal compressors, turbines, and many other pneumatic systems due to their simplicity of design, reliability, low cost. The calculation scheme for the movement working medium a labyrinth seal is constructed by analogy with through holes sharp edge. Annular flat slots, holes, such factor as shaft rotation calculated sector 3 degrees were studied. purpose ...

The centrifugal compressor is the core component of supercritical CO2 power cycle, and its performance operation stability are research hotspots. However, there few experimental studies, especially for compressors used in Mwe-scale cycles. In this paper, based on a 1 MWe single-stage designed with speed 40,000 RPM, pressure ratio 2.5 mass flow 16.3 kg/s. order to carry out test, general platfor...
