Steam Basics | CleanBoiler.org

The use, whatever that happens to be, is called Heat Transfer. This is the third stage. In the heat transfer portion of the steam loop, the heat of the steam is, well, transferred. In other words, it is put to work doing countless jobs. As the steam gives up its heat through heat transfer or use, it condenses or changes its state - this time

Vacuum Transformer Drying Ovens | HERING VPT: The standard

Generally there are three steps to the process: the heating-up phase, the evacuation of the autoclave and cooling. The two methods only differ in the heating up phase (hot air and vapor-phase). Due to different magnitudes of heat transfer, the vapor-phase drying process allows for faster drying, whereas the hot-air process is easier to implement.

Sublimation (phase transition) - Wikipedia

Sublimation is the transition of a substance directly from the solid to the gas state, without passing through the liquid state. Sublimation is an endothermic process that occurs at temperatures and pressures below a substance's triple point in its phase diagram, which corresponds to the lowest pressure at which the substance can exist as a liquid.The reverse process of sublimation is

How to calculate the heat duty for heat exchangers

The equation to calculate the heat duty is normally written in two ways. One that can be used for sensible heat transferred, this means that the fluid undergoes no phase change. The other can be used for latent heat transferred, this means that the fluid undergoes a phase change. i.e. condenses.

Phase Change: Cooling and Solidification of Metal | COMSOL

Phase change is a transformation of material from one state of matter to another due to a change in temperature. Phase change leads to a sudden variation in the material properties and involves the release or absorption of latent heat. We can use the Heat Transfer Module to model this type of phase change. Let's start with an example.

These changes of phase always occur with a change of heat. Heat, which is energy, either comes into the material during a change of phase or heat comes out of the material during this change. However, although the heat content of the material changes, the temperature does not. Here are the five changes of phase.

optics - Does light change phase on refraction? - Physics

Conversely, when light goes from a high refractive index medium to a low refractive index medium (such as water to air) it DOES NOT undergo a phase change. This is a general property of waves. See: Phase shift of 180 degrees on reflection from optically denser medium. The 'refracted' wave does not undergo a phase change either way.

Why Temperature Remains Constant during a Phase Change

By Steven Holzner . Thanks to physics, we know that phase changes occur when materials change state, going from liquid to solid (as when water freezes), solid to liquid (as when rocks melt into lava), liquid to gas (as when you boil water for tea), and so on. When the material in question changes to a new state — liquid, solid, or gas (you can also factor in a fourth state: plasma, a
