Air-atomized Fog-jet Cooling of Hot Billets

Cooling Down Hot Air A Global

The Kyoto Protocol marks a break-through in global warming mitigation policies as it sets legally binding emissions targets for major emitting regions. However, realisation of the Protocol depends on the clarification of several issues one of which is the permissible scope of international emissions trading between signatory countries. Unrestricted trade produces hot air when signatory countrie...

Flapping Instability of an Atomized Liquid Jet

We present an experimental study of the flapping instability which appears when a coaxial liquid jet is atomized by a cocurrent fast gas stream. When primary atomization does not lead to a total break-up of the liquid jet, it undergoes a largewavelength instability, characterized by very large amplitude oscillations, and can break into large liquid fragments whose typical size is the jet diamet...

Thermo-Economic Analysis of Applying Cooling System Using Fog on GE-F5 Gas Turbines (Case Study)

Presently, nearly 26,000 MW gas power plant and nearly 16,000 MW of combined cycle has been installed in the country. But their power output in summer reduces to a minimum, where most demand is required, compared to the winter season. The main reason for that is gas turbine dependence on the ambient air temperature. Since most of our country has warm and dry climates, cooling down the input air...

Heat and Mass Transfer in a Permeable Fabric System under Hot Air Jet Impingement

Heat and mass transfer in a permeable fabric system used for Personal Protective Equipment (PPE) was investigated using hot air jet impingement conditions to mimic the jet exhaust of Short Take-Off and Vertical Landing (STOVL) aircraft. The STOVL aircraft uses a thrust-vectoring nozzle of the jet engine and a lift fan in order to vertically land and take off a short runaway. The jet engine exha...
