In the report of the project for the company Esotech d.d. Velenje the results of research on the influence of dispersed solvent droplet flow in the wet tower on the flow conditions in flue gas are presented. The parametric analysis of different designs of spray nozzle systems showed, that the nozzle positions significantly influence pressure drop characteristics of the wet tower, as well as heat and mass transfer between the droplets and flue gas. The developed numerical model is based on Lagrange-Euler approach and can be extended to include also mass transfer through absorption.

COBISS.SI-ID: 14058518In this paper a numerical scheme for simulation of flow of nanofluids is presented. Governing equations for flow and heat transfer in nanofluids are written in velocity-vorticity formulation. Integral form of the equations is derived using the boundary element method. After discretization an over-determined system of linear equations is formed. The validity of derivation and the accuracy of the scheme is confirmed by comparing benchmark test cases with published reference data. A study of influence of nanofluids for heat transfer enhancement in natural convection is presented.

COBISS.SI-ID: 14368022In the design process for automotive headlamps it is important to understand the flow and radiation condition around the light bulb. In this study, we present the boundary conditions for simulation of the whole headlamp – temperature, heat flux and radiation flux of a H7 bulb. Results are validated by temperature measurement taken with thermal imaging system.
