throttling
Thread Content
Does the temperature of the material definitely decrease after throttling? Is there a difference in the degree of cooling for different materials?
Throttling measures can reduce the flow velocity of the material in the pipeline, thereby minimizing material loss and energy consumption, but they do not necessarily lower the temperature of the material. Different materials have different thermal properties, and the degree of temperature drop also varies. For example, the temperature of some volatile liquids may rise after throttling, as their heat of vaporization is converted into thermal energy due to friction, resulting in an increase in temperature ； For other materials, however, the temperature may drop. Therefore, it is necessary to determine whether throttling measures are required and how to implement them based on the specific properties of the material and its usage conditions, in order to achieve the best results. .

This temperature drop is manifested as a decrease in pressure after throttling; the fluid must adapt to the temperature resulting from throttling, and the changes in pressure of this fluid lead to changes in energy and temperature. This is also the reason why, when using carbon dioxide fire extinguishers, it is necessary to prevent \"burns\" (i.e., frostbite). For reference.
