Thermodynamic Study on Blends of Hydrocarbons and Carbon Dioxide as Zeotropic Refrigerants

Autor: Yiannis A. Levendis, Hameed Metghalchi, Sai C. Yelishala, Reza Sadr, Ziyu Wang, Kumaran Kannaiyan

Publikováno v: Journal of Energy Resources Technology. 142

Finding alternative refrigerants is of extreme importance to mitigate anthropogenic climate change. Among the next-generation refrigerants, hydrocarbons (HCs) are of technical interest because they are natural, efficient, have low global warming pote

Flame characteristics of propane-air-carbon dioxide blends at elevated temperatures and pressures

Autor: Ziyu Wang, Sai C. Yelishala, Hameed Metghalchi, Zhenyu Lu, Yiannis A. Levendis

Publikováno v: Energy. 228:120624

Propane (C3H8) is being considered as an alternative refrigerant, besides being used as an alternative fuel, because of its low Global Warming Potential and zero Ozone Depletion Potential. Using blends of C3H8 with CO2 as refrigerants, diminishes the

Laminar burning speeds and flame instabilities of isobutane carbon dioxide air mixtures at high pressures and temperatures

Autor: Hameed Metghalchi, Sai C. Yelishala, Yiannis A. Levendis, Zhenyu Lu, Ziyu Wang

Publikováno v: Fuel. 268:117410

Liquefied petroleum gases (LPGs), such as isobutane and propane, find applications as working fluids in refrigeration and as fuels in internal combustion engines. Isobutane is typically used as a precursor molecule in the synthesis of isooctane, a co
