IntroductionState-of-the-art gas turbine engines usually work under extremely high temperatures. This is directly related to efficiency of the gas turbines – in order to...
Part 1Gas Turbine Development Trends: Hydrogen EnergyRecent world trends related to the development of clean energy have led to an increased focus on...
One of the important factors affecting compressor performance is the distribution of work between compressor stages.There can be many different axial compressors with the...
Why Use an Inducer? Suppose you want to build a turbopump to increase the pressure of your working fluid. However, you find that the fluid that you are working with keeps vaporizing in the impellers you design, causing all sorts of performance issues. What can you do in this case? One solution is to design Read More...
Most designers associate drilled nozzles in turbomachinery with something exotic, uncharted, and specific only to a minuscule amount of high-loaded turbines operating with a high-pressure drop. Meanwhile, many engineers are not aware that this nozzle design has been applied since the very first turbomachines. Karl Gustaf Patrik de Laval patented a turbine with asymmetric convergent-divergent Read More...
Introduction Fuel cells are an important driver in the current energy system landscape with significant impact on the technology base and economic growth. Global fuel cell system shipments saw a 10% increase in 2020, totaling 1.3GW. The transport sector continues to lead with a growth of 25% on the number of units shipped globally. The Read More...
When you think of shock waves, I would wager that you picture a supersonic jet zooming past overhead. Or maybe you have experienced the famous (or infamous) “sonic boom” that accompanies shock waves attached to airplane engines. The engineering challenges associated with the often-troublesome behavior of shock waves is present in all scales, from carefully Read More...
Introduction Despite the deepening understanding of the essence of gas-dynamic processes and the development of computational methods, simpler design methods such as scaling and trimming remain in demand in turbomachinery engineering. The main advantage of these approaches over design from scratch is simplicity and its inexpensive nature due to the small-time expenditure and lower demand Read More...
