EXHAUST EMISSIONS OF JET ENGINES POWERED BY BIOFUEL [PDF]

Transport Problems, 2021
Biofuel use is one of the basic strategies to reduce the negative impact of aviation on the environment. Over the past two decades, a number of biofuels produced from plants, lubricants and maintenance products have been developed and introduced. New fuels must have specific physicochemical parameters and meet stringent standards. This article presents

Power exhaust by core radiation at COMPASS tokamak

Nuclear Fusion, 2021
Abstract Substantial power dissipation in the edge plasma is required for the safe operation of ITER and next-step fusion reactors, otherwise unmitigated heat fluxes at the divertor plasma-facing components (PFCs) would easily exceed their material limits.

Görtler Vortices in the Shock Wave/Boundary-Layer Interaction Induced by Curved Swept Compression Ramp

Aerospace
This study builds on previous research into the basic flow structure of a separated curved swept compression ramp shock wave/turbulence boundary layer interaction (CSCR-SWBLI) at the leading edge of an inward-turning inlet.

Mitigation of divertor edge localised mode power loading by impurity seeding

Nuclear Fusion, 2023
One of the major challenges for the design of future thermonuclear reactors is the problem of power exhaust—the removal of heat fluxes deposited by plasma particles onto the plasma-facing components (PFCs) of the reactor wall. In order for the reactor to

Effect of exhaust thermal parameters on optimal circuit layouts and optimal thermoelectric generator structure used in internal combustion engine

Energy Conversion and Management: X, 2023
To improve the thermoelectric generator (TEG) power conversion efficiency when recovering automobile exhaust waste heat, it is important to design an optimal structure and circuit layouts on TEG responding to actual changed exhaust parameters.

Direct Numerical Simulation of Boundary Layer Transition Induced by Roughness Elements in Supersonic Flow

Aerospace
Current research on the transition mechanisms induced by moderate-height roughness elements remains insufficiently explored. Hence, direct numerical simulation (DNS) and BiGlobal stability analysis are employed in this study to investigate boundary layer

SOLPS-ITER simulations of an X-point radiator in the ASDEX Upgrade tokamak

Nuclear Fusion, 2022
The X-point radiator (XPR) is an attractive scenario that may contribute to solving the power exhaust problem in future fusion devices. The 2D transport code SOLPS-ITER was applied to reproduce the experimentally measured plasma condition with an XPR in ...

Influence of porous plate position on thermoelectric generator

Energy Reports, 2022
Thermoelectric generators can be used to utilize the waste heat from vehicle exhaust for power generation. Due to the poor heat transfer of the exhaust, the thermoelectric conversion efficiency of the generator is poor, thus strengthening the heat ...

Multispectral compatible camouflage metamaterial with dynamic multilevel infrared tunability

Case Studies in Thermal Engineering
With the development of camouflage technology and the increasingly intricate battlefield environment, single-band and untunable devices can no longer cope with the existing demand for integration and miniaturization. Using a simple structure to integrate
