Loss of particle ratio metric for particle image velocimetry accuracy estimation
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2025)This paper presents an algorithm for evaluating measurement uncertainty at individual points within the Particle Image Velocimetry (PIV) method. The algorithm presents a novel correlation plane metric known as the Loss of ... -
Effects of coupled diffusion and buoyancy forces on three-dimensional MHD convective Williamson-Casson nanofluid flow: a numerical study
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2025)The study analyses how thermal diffusion, Dufour effect, thermophoretic forces, Brownian motion, buoyancy-driven convection, and magnetic fields collectively impact microbial behaviour in a convective MHD flow of a ... -
Mathematical modelling and analysis of three-dimensional Maxwell-Nanofluid flow over a bidirectional stretching surface in the presence of a magnetic field
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2025)The current study investigates the effects of thermal diffusion and diffusion thermoeffect on three-dimensional upper-convected Maxwell-Nanofluid flow across a bidirectional stretching surface in the presence of Brownian ... -
Direct current nanogrid providing energy for water pumping: a comparative study in a riverside community in the Amazon
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2025)Water pumping systems are crucial for improving the quality of life for riverside communities. In the Amazon, most of these systems still rely on fossil fuels. However, new off-grid electrification structures using Direct ... -
Simulation of an active cooling system for low-concentratinag photovoltaic solar cells
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2025)One of the key challenges of concentrating photovoltaic (CPV) systems is the need for effective thermal management, as the increased solar irradiance significantly raises the operating temperature of solar cells, thereby ... -
Improving the production process of silicon nanoparticle and quartz microlens
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2025)This study presents a comprehensive investigation into advanced laser micro/nano machining techniques, utilising three distinct laser sources: a Q-switched Nd:YAG laser, a fibre laser, and a CO2 laser.
