The effect of changing superheat degrees on energy consumption in a split air conditioning
Journal of Physics: Conference Series, 2020 Abstract Split air conditioning is the most widely used in the community for both commercial and domestic purpose. But it can cause inefficiency or waste of energy use by the system. For this reason, it is very important to keep the system working in optimum conditions to prevent wasteful use of energy by the air conditioning system ...

Effect of gaseous CO2 on superheated steam flow in wells
Engineering Science and Technology, an International Journal, 2017 In this paper, a novel model is proposed for estimating pressure and temperature in wellbores when CO2 and superheated steam (SHS) are co-injected. Firstly, a model comprised of mass, energy and momentum conservation equations are developed.
