• Abstract:

  Many engineering situations involve boiling processes. In the case of nucleated boiling, a more in-depth study is needed to improve its technical use of intensification and be able to minimize the risks.

  involved in confinement when it is imposed by the

  project, as this can lead to problems linked to the premature triggering of the critical flow, which represents the limit at which the system is operated in nucleated boiling. This course conclusion work aims at the design and construction of a nucleated boiling chamber having its working pressure limited to 60 bar. For the construction of the nucleated boiling chamber, the materials used are a mechanical tube used for the body of the equipment, and the other parts all made of SAE 1020 steel, being manufactured by the machining process, the union of the parts where necessary is made by screws with or without nuts and locknuts or by welding process. The chamber has two tempered glass hatches so that it can be seen inside during the tests carried out, thus being able to see

  what happens in the refrigerant used for testing
