Non-equilibrium effects on in-tube condensation from superheated vapor
In a vapor-compression system, refrigerant leaves compressor as superheated vapor. After entering the condenser, energy is transferred out of the refrigerant flow. As a result, the thermodynamically averaged temperature, namely the bulk temperature, of the refrigerant decreases. Conventionally when …

Functional nanostructured hydrothermal carbons for sustainable technologies : heteroatom doping and superheated vapor
… °C) and pressure (50 bar), corresponding to the superheated vapor regime (htHTC). It was demonstrated that the carbon materials obtained via htHTC are distinct from those obtained via ltHTC and subsequent pyrolysis at 550 °C. No difference in htHTC-derived material properties could be observed …

An investigation of the effect of entrained oil on the heat transfer rate of a refrigerant evaporator
… transfer characteristics of a direct expansion evaporator coil. A modified refrigeration system, in which the oil content of the refrigerant could be varied, was used in conjunction with an air conditioning system, which supplied the evaporator load. The heat transferred to the refrigerant was …

Multiple Sulfur Isotope Systematics of Geothermal Fluids at Krafla, NE Iceland, and the Source and Reactions of Sulfur in Volcanic Geothermal Systems
… ranged from 192 to 437°C with liquid water, vapor and superheated vapor being present in the reservoir. Dissolved sulfide (ΣS-II) and SO4 predominated in the water phase with trace concentrations of S2O3 whereas H2S was the only species observed in the vapor phase. The reconstructed sulfur …

Investigation of oil retention and pressure drop in suction lines using R134a with AB ISO 32
… operation, by the high velocity refrigerant vapor exiting it, which forms a mixture with the oil. This circulating refrigerant/lubricant mixture affects the system performance in terms of heat transfer coefficient and pressure drop. The circulating liquid mixture possesses the maximum …

Heat transfer and pressure drop in the condensing superheated region with visualization and film thickness measurement
… reaches saturation, even in the presence of superheated vapor. Similarly, condensation continues if some vapor remains even when the bulk refrigerant enthalpy is indicating a subcooled state. These two situations make a fourth and fifth zone in the condenser, classified as the condensing …

Nonsmooth Distillation Models Robust to Convergence Errors: Numerical Methods and Topological Aspects
… more stages operate with a single phase, either superheated vapor or subcooled liquid. By developing continuation methods to simulate the nonsmooth MESH model, we discovered a new class of degenerate bifurcations in distillation columns which are generally observed regardless of the mixture or …
