Effects on endwall heat transfer by a winglet vortex generator pair mounted upstream of a cylinder

The present study was conducted to investigate heat transfer enhancement from the endwall of a protruding circular cylinder by addition of a winglet vortex generator pair. A steady-state liquid crystal thermography technique was employed. The vortex generator pair is installed upstream of a cylinder placed either in counter flow inward or counter flow outward orientation. The vortex generator inst

Computational optimization of fuel supply, syngas composition, and intake conditions for a syngas/diesel RCCI engine

By utilizing the promising alternative fuel of syngas, and the syngas/diesel dual-fuel reactivity controlled compression ignition (RCCI) is a potential combustion strategy for internal combustion engines. However, the optimal operating parameters for syngas/diesel RCCI engines under wide operating conditions have not been investigated. In this study, the operating parameters include fuel supply, s

Evaluation of groundwater discharge into surface water by using Radon-222 in the Source Area of the Yellow River, Qinghai-Tibet Plateau

Understanding hydrological processes in the Source Area of the Yellow River (SAYR), Qinghai-Tibet Plateau, is vital for protection and management of groundwater and surface water resources in the region. In situ water measurements of exchange rates between surface water and groundwater are, however, hard to conduct because of the harsh natural conditions of the SAYR. We here present an indirect me
