Hermetic reciprocating compressors are widely used in small- and medium-size refrigeration systems based on the vapor-compression cycle. One of the main parts of this type of compressor is the automatic valve system used to control the suction and di

In the present work, an extension of the Fourier Pseudospectral Method coupled with the Immersed Boudary Method for non-periodic problems (IMERSPEC) applied to numerical simulation of two-phase flow was developed. The proposed method was originally d

With the usage of a robust and efficient method, validated with literature data, numerical experiments were developed to analyze isolated rising bubbles and quantify fluid dynamic forces acting on them. An integral method is presented and used for th

An extension of the Oberbeck–Boussinesq approximation (OB) with expressive thermal effects is investigated to model specific mass with a temperature-dependent approach. An expansion of OB is proposed using a mathematical formulation with null veloc

A variety of frameworks to model two-phase flows with surface tension are available, each with its individual advantages and disadvantages. The understanding of the implications of the different frameworks is essential to conduct accurate and reliabl
