The impact of the use of cargo bicycles for delivery processes on the environment is
undeniably positive: it leads to the reduction of pollutants, noise, and vibrations caused by …

The necessity of two-stage (multi-cyclone-baffle) inlet air filters used for motor vehicle
engines operating under dusty conditions was demonstrated. The advantages of a set of …

Increasing the market share of low-emission vehicles in relation to individual mobility is one
of the main postulates of modern transport policy. In the discussion on low-emission and the …

Currently, numerous methods are introduced to reduce the loss of mechanical energy of the
engine using various materials for anti-wear coatings. The paper presents the results of …

This article studied the effect of the inlet velocity and various geometric dimensions on the
flow pattern, collection efficiency, pressure drop, and acoustic noise of axial cyclones using …

Respirable dust in coal mines endangers the health of workers. To detect its concentration
accurately and separate it effectively from the total dust volume is the first priority. In this …

When dewatering and resurrecting natural gas-flooded wells, sand-out problems can pose a
serious hazard to downhole tools. At present, the downhole cyclone has more research on …

This work presents a high-fidelity surrogate model for generating a multi-objective genetic
algorithm to allow the search for the optimal geometry of the inlet channel and the basin of a …

A spiral-channel dust separator was investigated experimentally and numerically for its
efficiency to separate black powder from natural gas pipelines. Effects of gas flowrates and …

The aim of this work is to develop a model of heat supply to buildings with almost zero
energy consumption, indicating the significant importance of heat losses and gains in …
