The work focuses on energy conversion during the internal flow, discharge and formation of the spray from a pressure-swirl (PS) atomizer in the simplex as well as spill-return mode. Individual energy forms are described in general and assessed experimentally for a particular PS atomizer and...

This study is a contribution to the analysis of energy production by hybrid systems using renewable energy sources. It is realized within the framework of an isolated site, i.e., without any connection to an electrical network. Generally, with the conventional solutions for energy production,...

The present work considers a T-shaped standing-wave thermoacoustic system with an electrical heater confined in the bottom stem and two temperature-controllable heaters (TCHs) enclosed in the bifurcating branches. With the heater placed at the bottom stem set to 1100K and TCHs be adiabatic,...

The effect of how a wind turbine generator system is operated is discussed from the viewpoint of net power extraction with wind velocity fluctuations in relation to the scale and the dynamic behavior of the system. On a wind turbine generator system consisting of a Darrieus-Savonius hybrid wind...

This paper treats the design and control of two hybrid source using supercapacitors, fuel cell, with and without batteries on the DC link. A fuel cell, as a slowest dynamic source in these systems (because of its auxiliaries) acts to supply the permanent energy. The supercapacitors, as a high...

The analysis of reversible radiation conversion is insightful in process optimization and provides the upper limit to performance of any conceptual device. However, in practice, irreversibilities are unavoidable and play an important role in performance optimization. The finite absorption of a...

Thermal energy storage is essential in solar cooling applications due to intermittent and uncontrollable availability of solar energy. Various technologies are available for low temperature energy storage. In the present work, a solar-assisted ejector cooling system with latent heat cold storage...

The gaming and hospitality sector has been expanding rapidly in recent years. Concurrently energy consumption in this sector has surged significantly. This paper reviews the literature on the relationship between electricity consumption and economic growth and introduces the 4-parameter logistic...

This paper assesses the steady-state performance of cascaded IMs (induction motors) operating under voltage unbalance. Small sizes induction motors are connected in cascade instead of one big size induction motor to improve the electromagnetic system and to make the energy conversion process...
