  • Research scientist at Institute of Chemical Process Fundamentals
    2004 - Jun 2018 · 14 yrs 6 mos

    Research: Fluid mechanics, focused on multiphase flows: Dynamics of bubbles and drops, surfactants, turbulence. Writing research papers (see https://scholar.google.cz/citations?user=zg0-FZQAAAAJ). Responsible for research projects funded by grant agencies. Building experimental stands: Experimental stands for measurement of permeation of gases through membranes, applied for: 1. biogas upgrade, 2. volatile organic compounds (VOC) separation, 3. cleaning of flue gases. Image and data processing: Developed MATLAB code for measurements of velocity field using the particle-image-velocimetry (PIV) method (PIVsuite, http://www.mathworks.com/matlabcentral/fileexchange/45028-pivsuite). Other software for image processing, signal processing, solving systems of ordinary differential equations.
