In this book the author presents selected challenges of thermal-hydraulics modeling of two-phase flows in minichannels with change of phase. These encompass the common modeling of flow boiling and flow condensation using the same expression. Approaches to model these two respective cases show, however, that experimental data show different results to those obtained by methods of calculation of heat transfer coefficient for respective cases. Partially that can be devoted to the fact that there are non-adiabatic effects present in both types of phase change phenomena which modify the pressure drop due to friction, responsible for appropriate modelling. The modification of interface shear stresses between flow boiling and flow condensation in case of annular flow structure may be considered through incorporation of the so called blowing parameter, which differentiates between these two modes of heat transfer. On the other hand, in case of bubbly flows, the generation of bubbles also modifies the friction pressure drop by the influence of heat flux. Presented are also the results of a peculiar M-shape distribution of heat transfer coefficient specific to flow boiling in minichannels. Finally, some attention is devoted to mathematical modeling of dryout phenomena. A five equation model enabling determination of the dryout location is presented, where the mass balance equations for liquid film, droplets and gas are supplemented by momentum equations for liquid film and two-phase core.

This thesis aims at contributing to the planning of the process kinematics for thermal spraying under consideration of the heat and mass transfer to the component. The objective of the work is to develop concepts for robot trajectory generation, which lead to a better control of the coating properties, by controlling the parameters defined by the process kinematics and the related phenomena, such as the heat transfer to the substrate. Two approaches of off-line programming are considered to give a solution to the problem exposed above. A model to minimise the temperature gradients within the substrate is created, considering the coating of planar substrates. A mathematical model of the heat transfer during spraying is developed and used for the optimisation of the spray path in order to produce low temperature gradients in the composite. Furthermore, trajectory generation to coat complex shaped components is considered. For that case, an increase in the degrees of freedom of the handling system is made by implementing an external rotational axis, which positions the substrate during the deposition process and allows the maintaining of constant kinematic parameters in order to obtain homogeneous coatings.
