Opis:: The paper presents selected problems of numerical modelling of an advanced thermal- FSI (Fluid solid interaction) approach of evaporator of air heat pump. The example of a fin-tube evaporator has been studied, focusing on obtaining the heat exchanger characteristics applying two-phase flow model for the in-tube refrigerant flow. Special attention is given to heat transfer between separated medium for different air velocity and changed refrigerant mass flow in-tube.

Opis:: The hydroacoustic signatures of ship propellers can be identiﬁed experimentally through measurements of cavitation-induced pressure ﬂuctuations and the accompanying noise distribution at model scale. These measurements have to be performed in a cavitation tunnel at the propellers operating conditions and with suﬃcient accuracy. In comparison, the numerical approach can be used to present a good general idea of the predicted results. Numerical methods can provide highly accurate tools for noise level and propagation prediction, as well as giving insight into the ﬂow ﬁeld and other key aspects. They are also not inﬂuenced by signal conditioning or disturbance sources present in a physical environment. So we trade scope and precision of the results for time and cost reduction. In this paper, we described both experimental and numerical methods currently in use and present advantages and limitations of the practical application of both.
