Special Issue Information

Dear Colleagues,

This Special Issue is the second edition of "Advanced Engine Technologies and Innovative Vehicle Driving Systems".

The issue will be focused on the newest technologies developed for improved combustion as well as for emission mitigation, namely advanced combustion engine technologies based on the application of alternative fuels and innovative vehicle driving systems. The main purpose is to offer a comprehensive platform for publishing scientific research results concerning:

The research and development of piston combustion engines with application of bio-fuels;
Innovative driving systems of vehicles based on alternative drives, especially hydrogen drives;
The development of advanced systems for reducing engine gaseous emissions;
Simulation approaches to the above-mentioned issues in order to investigate and optimize engine combustion processes and the operation of alternative drives;
Environmental aspects of alternative drives compared to combustion engine drives.

Dr. Michal Puškár
Guest Editor

Abstract

In this article, an analytical solution to a hydraulic network with a wide range of pipe lengths (up to 10 km) is proposed. The Finite-Difference Time-Domain (FDTD) method was applied with the aim of creating a regulation model for controlling both the flow rate of water from one of the two sources and the discharge pressure in the system. The system inertia requires an understanding of boundary conditions in the operation of pipeline networks, which must be known in order to regulate the required parameters with only minor deviations. The proposed model was compared to experimental data, while the mean absolute deviations in the individual system branches ranged from 1 to 5.19%. The created regulation model was subsequently tested by applying linear, sine and stochastic changes in the output load, while the ability to control the discharge pressure and the selected water flow rate was analysed. The effect of coefficient ε, which multiplies the effect of the difference between the measured and the predicted value of the discharge pressure on the boundary conditions of the discharge pressure in the system, was analysed in this paper. With the use of the proposed unsteady simulation of the fluid flow in the hydraulic system arranged in parallel and in series, the maximum deviation of the regulated pressure was 1.2% and the maximum deviation of the regulated flow rate was 5.3%.
