Thermal performance analysis of Al2O3/R-134a nanorefrigerant

Investigation and analysis of lubricant effects on the performance of an HFC-134a refrigeration system

Some Thermodynamic Performance Test Results of Refrigerant 134a

As part of an ongoing investigation into environmentally acceptable alternatives to the CFC refrigerants a series of tests have been completed comparing the thermodynamic performance of Rl34a with Rl2. The tests were carried out under controlled conditions in a well instrumented water/water heat pump test facility, using an open-drive reciprocating compressor and counter flow heat e%changers. B...

Thermal Analysis of Tire

One of the great enemies of rubber compounds is heat. Heat will cause chemical and physical degradation of vulcanized rubber as well as a considerable loss in its strength. A major source of heat generation in a tire is due to internal friction resulting from the viscoelastic deformation of the tire as it rolls along the road. Another source of heat generation in a tire is due to its contact fr...

Analysis of the Thermal Comfort Properties and Heat Protection Performance of Cotton/Nylon-Kermel Fabrics

In this research, fire and radiant heat protection and thermal comfort properties of cotton/nylon-Kermel blended woven fabrics, were utilized to predict the thermal comfort and protection limit of this fabric structure based on Woo and Barker developed model. The results showed that the porosity, the air permeability and the thermal resistance increased with Kermel fiber blend ratio. Conversely...
