There is a little trick that I\u2019m explaining here related to the functioning and thermal transfer efficiency of heat exchangers<\/a><\/strong>: why the performances increase while the pressure drop increases<\/strong>?<\/p>\n

The thing is simple: when we allow increased pressure drops on the fluid\u2019s flow rate<\/strong> within an exchanger, and thus pressure drop of water circulating within the shell or the tubes, or on the two sides of a plate heat exchanger, we obtain a boost in performances<\/strong>. That\u2019s because, being equal the section of the exchanger, increasing the pressure drop means that we are increasing the flow rate<\/strong>. Even better said, when we are accepting higher pressure drops, that means that we can reduce the passage section of the fluids and thus increase their flowing speed<\/strong>.<\/p>\n

That leads to a more turbulent flow<\/a> of fluids<\/strong>, which in the exchanger involves a higher number of collisions among the particles of the fluid and thus a higher thermal transfer rate<\/strong>. That\u2019s why the thermal transfer efficiency increases too.<\/p>\n
