The H411 is a floor-mounted unit designed to provide a visual demonstration of the flow boiling processes that can occur inside the vapour generating tubes of practical plant such as refrigeration, steam, chemical and food processing systems.
A real (not simulated) boiling process is used and all the stages of evaporation from warming of sub-cooled liquid to nucleation, bubble flow, slugging, annular flow, droplet entrainment and finally superheated vapour can be observed and demonstrated. The unit operates under steady state conditions allowing the processes to be studied for prolonged periods of time.
Floor mounted, vertical, glass, concentric tube heat exchanger for the observation of all stages of heat transfer as a pure substance changes from sub-cooled liquid to superheated vapour.
