In Thermodynamics: “What Goes Around-Comes Around” is a Good Thing

When discussing the efficiency of transforming one form of energy to another, circularity is the way to go. Anyone who has spent even a little time studying engineering thermodynamics knows that the continuous transformation of energy from a heat energy source to produce mechanical or electrical power must contend with components that operate in a cycle. The key word here being “continuous”. The combustion of any carbon-hydrogen bond material (i.e., fossil fuels), or the liberation of heat energy from any number of materials when placed in a piston-cylinder, would not be very useful if the piston is not returned to its initial “precombustion” position. It is literally the difference between the one-time launching of an object from the cylinder or the continuous production of rotary shaft power; power that can be used to propel a vehicle forward or turn an electric generator. It is the cyclic operation of the fluid in the thermodynamic cycle that enables heat engines and refrigeration cycles to provide continuous power, or cooling, that is needed for the safety, security, comfort and all the other “hierarchy of needs” that was so well formulated by the renowned humanist psychologist, Dr. Abraham Maslow.

The Future of Turbomachinery Software

by Mark R. Anderson on Sep 9, 2016 11:27:00 AM

The turbomachinery and software industries have evolved, in tandem, to high levels of maturity. On the engineering side, improved modeling capability and access to more powerful computational resources have revolutionized the design process, reducing costs and significantly improving performance and reliability. On the manufacturing side, additive manufacturing is starting to open up exciting new possibilities by allowing component shapes that simply were not possible before. 

Like all technology, the evolution of these methods may seem clear enough for the near future, but it can be much more hazy over the long-term. Therefore, this article will take a look at what the future of  turbomachinery software may hold.
