Cooling and air-conditioning installations utilize the change of cooling agent parameters (pressure, temperature and state) when it circulates between the evaporator and the condenser in the cooling system. The cooling agent circulates driven by the refrigerating compressor. The refrigerant absorbs heat by evaporation in the evaporator, then it gives up heat when vapour is condensed in the condenser. There are many types of refrigerants (water, carbon dioxide, ammonia), however there is one special type of low-boiling hydrocarbons, called freons. Flexible freon hoses are widely used in air-conditioning systems of various vehicles (cars, machinery, trains, trams) as well as in smaller installations of industrial cooling. In these installations, freon (e.g. R134a, R1234yf) mixed with compressor oil (e.g. PAG synthetic oil) acts as a refrigerant. It circulates in the system where it undergoes continuous pressure and temperature fluctuations. Therefore, requirements concerning freon hoses are so high. It is essential for the system to be perfectly tight as freon is very penetrating, expensive and harmful to the environment. It must be highly resistant to pressure, temperature, chemicals and stop humidity from permeating the hose wall. It concerns automotive air-conditioning in particular because there, the freon hose operates in the engine compartment, tightly packed and bent, in high ambient temperature conditions, exposed to vibrations and in contact with car fluids.

The authors provide a brief overview of the classic tonal screech noise problem created by underexpanded supersonic jets, briefly describing the fluid dynamic-acoustics feedback mechanism that has been long established as the basis for this well-known aeroacoustics problem. This is followed by a description of the Long Penetration Mode (LPM) supersonic underexpanded counterflowing jet phenomenon which has been demonstrated in several wind tunnel tests and modeled in several computational fluid dynamics (CFD) simulations. The authors provide evidence from test and CFD analysis of LPM that indicates that acoustics feedback and fluid interaction seen in LPM are analogous to the aeroacoustics interactions seen in screech jets. Finally, the authors propose applying certain methodologies to LPM which have been developed and successfully demonstrated in the study of screech jets and mechanically induced excitation in fluid oscillators for decades. The authors conclude that the large body of work done on jet screech, other aeroacoustic phenomena, and fluid oscillators can have direct application to the study and applications of LPM counterflowing supersonic cold flow jets.

Molten salt reactor schematic from GenIVMolten Salt Reactors (MSRs) are nuclear reactors that use a fluid fuel in the form of very hot fluoride or chloride salt instead of the solid fuel used in most reactors. Since the fuel salt is liquid, it can be both the fuel (producing the heat) and the coolant (transporting the heat to the power plant). There are many different types of MSRs, but the most talked about one is definitely the Liquid Fluoride Thorium Reactor (LFTR). This MSR has Thorium and Uranium dissolved in a fluoride salt and can get planet-scale amounts of energy out of our natural resources of Thorium minerals, much like a fast breeder can get large amounts of energy out of our Uranium minerals. There are also fast breeder fluoride MSRs that don’t use Th at all. And there are chloride salt based fast MSRs that are usually studied as nuclear waste-burners due to their extraordinary amount of very fast neutrons.

A Stirling engine is a heat engine operating by cyclic compression and expansion of air or other gas, the working fluid, at different temperature levels such that there is a net conversion of heat energy to mechanical work. Or more specifically, a closed-cycle regenerative heat engine with a permanently gaseous working fluid, where closed-cycle is defined as a thermodynamic system in which the working fluid is permanently contained within the system, and regenerative describes the use of a specific type of internal heat exchanger and thermal store, known as the regenerator. It is the inclusion of a regenerator that differentiates the Stirling engine from other closed cycle hot air engines.

Suppose that you wanted an interface of sortable, tiled information that was responsive enough to reorganize itself to fit in the available screen space? You might start out towards this goal filled with consternation, asking yourself: “how would I even start thinking about how to make such a complicated thing?” Well, the good news is that you don’t really have to, thanks to a jQuery plugin called Isotope developed by David DeSandro of Metafizzy. Take a look at the Isotope website and try resizing your browser window. Note that the tiles will reorganize themselves to fill in the available space.
