The Effect of the Rotating Disk Geometry on the Flow and Flux Enhancement in a Dynamic Filtration System
Autor: Jo Eun Park, Tae Gon Kang, Heejang Moon
Publikováno v: Membranes, Vol 13, Iss 3, p 291 (2023)
A numerical study was conducted to investigate the effect of rotating patterned disks on the flow and permeate flux in a dynamic filtration (DF) system. The DF system consists of a rotating patterned disk and a stationary housing with a circular flat

Thermal–Combustion Coupled Instability in Hybrid Rockets with Fuel Blowing
Autor: Jungpyo Lee, Heejang Moon, Jinkon Kim
Publikováno v: Journal of Propulsion and Power. 39:308-317
Thermal–combustion coupled instability creates one of the natural frequencies in hybrid rocket systems and is commonly observed as the dominant hybrid oscillation frequency. This type of instability is caused by the coupling between the thermal lag

Experimental investigation of the effects of paraffin/aluminum blended fuels on aluminum particle size
Autor: Seongjoo Han, Heejang Moon
Publikováno v: Journal of Mechanical Science and Technology. 33:3011-3018
The combustion behavior of paraffin/aluminum blended fuels was investigated to determine the effects on the size of nano- and micro-sized aluminum particles and assess their respective combustion performance in hybrid rocket applications. The base pa
