Effect of tangential swirl air inlet angle on the combustion efficiency of a hybrid powder-solid ramjet [PDF]

open access: yes, 2019
A new ramjet configuration using powder and solid fuel as propellant is investigated, namely, hybrid powder-solid ramjet (HPSR). Boron particles were used as the powder in this study.

Effect of coal mine organic aerosol on the methane/air lower explosive limit

open access: yesInternational Journal of Coal Science & Technology, 2020
Organic aerosol is formed in coal mines due to heat release and evaporation of organics from coal during the longwall operation. This frictional heating occurs when a metallic cutting bit strikes a rock.

Combustion noise

open access: yesProceedings of the Combustion Institute, 2015
AbstractCombustion noise is becoming increasingly important as a major noise source in aeroengines and ground based gas turbines. This is partially because advances in design have reduced the other noise sources, and partially because next generation combustion modes burn more unsteadily, resulting in increased external noise from the combustion.

Design and setup of a low calorific SOFC off-gas combustion chamber for a pressurized MGT hybrid power plant test rig [PDF]

open access: yesE3S Web of Conferences, 2019
A demonstrator system for a hybrid power plant is currently being built at DLR, designed for an electrical power output level of 30 kW. Since the very low energy dense exhaust gas of the fuel cell anode side represents the fuel for the combustion chamber

Beyond MHz image recordings using LEDs and the FRAME concept

open access: yesScientific Reports, 2020
Many important scientific questions in physics, chemistry and biology rely on high-speed optical imaging techniques for their investigations. These techniques are either passive, relying on the rapid readout of photoactive elements, or active, relying on
