Вестник Самарского университета: Аэрокосмическая техника, технологии и машиностроение, 2017 It is impossible to abandon the use of the afterburner combustion chamber in designing advanced gas turbine engines. Well-known and well-established structural designs of afterburners were developed several decades ago and do not meet the requirements ...

Afterburner: The Case for In-Browser Analytics
CoRR, 2016 This paper explores the novel and unconventional idea of implementing an analytical RDBMS in pure JavaScript so that it runs completely inside a browser with no external dependencies. Our prototype, called Afterburner, generates compiled query plans that exploit typed arrays and asm.js, two relatively recent advances in JavaScript.

Afterburning of solid rocket exhaust [PDF]
Acta Astronautica, 1974 AN EQUILIBRIUM CALCULATION of the solid fueled rocket exhaust of the proposed NASA Space Shuttle has been carried out and parameterized in terms of oxidant/fuel ratio. Results comparing the equilibration times with experimentally determined dilution times show that Hz and CO are completely burned to H20 and CO2, whereas HC1, although thermodynamical ly

steel research international, EarlyView.This study investigates the reduction behavior of two international iron ores, including a synthetic hematite produced by oxidation of magnetite, in a novel fluidized‐bed kinetic reactor at elevated pressures. The reduction takes place at various temperatures (650°C, 700°C, and 750°C), and various hydrogen partial pressures (30, 55, and 80 vol% H2 ...

Remediation Journal, Volume 36, Issue 2, Spring 2026.ABSTRACT Per‐ and polyfluoroalkyl substances (PFAS) are persistent environmental contaminants widely recognized for their resistance to degradation and potential adverse health effects. The treatment of PFAS‐contaminated aqueous media (e.g., drinking water, wastewater, and leachate) has been extensively studied in the published literature; however, the

Fuel Cells, Volume 26, Issue 5, October 2026.ABSTRACT This study presents a unified thermodynamic and exergy‐based assessment of autonomous fuel cell energy systems operating on biogas with varying compositions. Two alternative configurations—a solid oxide fuel cell (SOFC)‐based system and a proton exchange membrane fuel cell (PEMFC)‐based system—were evaluated using a common balance‐of‐plant ...
