Wet ethanol is a biofuel with unique fuel properties: a high latent heat of vaporization and low equivalence ratio sensitivity. These two fuel properties enable control over the heat release process in low temperature combustion through the enhancement of in-cylinder thermal stratification. In this ...
our design; however, to demonstrate the performance of our device for power amplifier applications, pentane and R245fa were selected as candidate dielectric working fluids for a combination of thermophysical properties including surface tension, latent heat of vaporization, viscosity, and vapor pressure....
subtracting the latent heat of vaporization of the water vapor formed by the combustion from the gross or higher heating value. Common Units Common units for heating value: 1 Btu/lb = 2326.1 J/kg = 0.55556 kcal/kg 1 J/kg = 0.00043 Btu/lb = 2.39×10-4 kcal/kg 1 kcal/kg = 1.80 Btu...
This heat energy is known as the latent heat of vaporization, and its removal cools the source it comes from. An example is the cooling of your body by evaporation of perspiration. What becomes of this heat energy used by evaporation? Energy cannot be created or destroyed, so it is hidden...
so did the fuel deposition on the quartz glass. Thereby hindering the light emitted by the combustion flames from being captured by the endoscope. As the viscosity and latent heat of vaporization of the lemon peel oil are higher than gasoline, the atomization and evaporation of the LPO blends ...
latent heat utilization for both passive16,17,23and active systems24,25. The main idea is to reuse the condensation heat, further driving the evaporation and condensation processes in subsequent stages. Since the inception of the vaporization enthalpy recycling concept26,27, the rapid progress of ...

Combustion gas is further cooled by the secondary heat exchanger to a temperature below its dew point, thereby extracting the latent heat of vaporization and producing water condensate. Cooling of the combustion gas results in heating of the water of the second water loop that circulates through ...

At an early age, heat capacity impacts heat generation, the heat of vaporization manages water phase changes, and thermal conductivity influences efficient heat transfer and hydration progress, manipulating the temperature-dependent characteristics of cement-based materials. These properties influence the ...
