“…In addition, the H2O and CO2 mass fractions at the outlet of this engine were higher. These data confirmed that more complete combustion would be expected to occur in this swirl−radial−injection fuel grain, based on using the mass fractions of CO2 and H2O as indicators of the extent of combustion [42]. The degree to which the combustion went to completion was quantified as a means of evaluating the efficiency of each design.…”

The combustion characteristics of a swirl-radial-injection composite fuel grain were experimentally and numerically investigated. This composite grain permits swirl-radial oxidizer injection based on three hollow helical blades, each having a constant hollow space allowing uniform oxidizer injection into the main chamber along the axial direction. The oxidizer enters from channel inlets located along a hollow outer wall. This wall, together with the three blades, is fabricated as one piece from acrylonitrile-butadiene-styrene using three-dimensional printing. Paraffin-based fuel is embedded in the spaces between adjacent blades. Firing tests were conducted with gaseous oxygen as the oxidizer, using oxidizer mass flow rates ranging from 7.45 to 30.68 g/s. Paraffin-based fuel grains using conventional fore-end injection were used for comparison. Regression rate boundaries were determined taking into account the erosion of the oxidizer channels. The data show that the regression rate was significantly increased even at the lower limit. Images of the combustion chamber flame and of the exhaust plume were also acquired. The flame was found to be concentrated in the main chamber and a smoky plume was observed, consistent with the high regression rate. A three-dimensional simulation was employed. The present design was found to improve fuel/oxidizer mixing and combustion efficiency compared with a fuel grain using fore-end injection. Both the experimental results and numerical simulations confirmed the potential of this swirl-radial-injection fuel grain.

Liquefied Petroleum Gas - Recent Advances and Technologies for Energy Transition [Working Title]

There is an urgent requirement for transition to better sustainable bioeconomy techniques due to global worries about the depletion of the fossil fuel supply in the world. Alternative fuels have gained interest as the world strives to create sustainable energy sources and reduce greenhouse gas emissions. BioLPG, a renewable shape of Condensed Petroleum Gas [LPG], has emerged as an attractive option in response to energy demands and environmental concerns. Using biomass feedstocks, such as agricultural residues, forestry waste, and waste cooking oil, bioLPG is a carbon-neutral alternative to traditional LPG. Compared with conventional LPG, bioLPG offers several benefits, including reduced net greenhouse gas emissions and lower carbon intensity. Moreover, bioLPG production can utilize multiple biomass feedstocks and maximize waste value. This chapter assesses the current state of research on bioLPG, identifies critical challenges and issues, and presents potential solutions for the broad adoption of bioLPG. BioLPG’s footprint varies and depends on the feedstock and situation in the European bases. However, it is often eligible for government support through financial credits and meets biofuel requirements by EU countries under the Renewable Energy Directive.
