A novel Chemical Looping Reforming (CLR) process is proposed in which a highly recyclable iron oxide composite particle is reduced with coal and then oxidized back with steam to generate hydrogen. The reduction of iron oxide with coal results in a mixture of CO2 and H2O in the exhaust stream which after water condensation provides a ready to sequester relatively pure CO2 stream. This eliminates...

in this study, confined impinging liquid jets are used to produce nanoparticles of carbamazepine (cbz). the effect of operating parameters, such as the kind of solvent,cbz concentration, flow rate of solution and antisolvent on particle size, are experimentally investigated. the scanning electron micrograph (sem) photomicrographs show that nanodrug with smaller particle is achievable by using s...

Background: A recently discovered mechanism of magnetic propulsion of a liquid metal in the toroidal magnetic eld of tokamaks (December of 1998) enables intense stationary liquid lithium (Li) streams covering the plasma facing surface of the vacuum chamber. There are several attractive properties of such a regime. These are presented, together with the possible issues, experimental foundations ...

Impinging jets are used in a wide number of industrial cooling applications due to their high heat and mass transfer abilities. The current research is concerned with the effect of swirl on the heat transfer characteristics of jet impingement cooling. Two inserts were designed order to generate swirling flow. These two designs, “Swirl Insert A” and “Swirl Insert B”, were tested at various Reyno...

This work aimed to test and optimise reactive Planar Laser-Induced Fluorescence (PLIF) methods for the visualisation of micromixing regions in chemical reactors using standard PLIF Particle Image Velocimetry (PIV) equipment with laser source 512 nm. Two were tested: (i) an acid–base reaction fluorescein as reaction-sensitive tracer (ii) Fenton’s reaction, Rhodamine B tracer. Both test-reactions...

The widespread use of renewable energy requires the support high-capacity storage systems. This work proposes a thermochemical system for concentrated solar power plants based on reversible hydration/dehydration process calcium hydroxide. It is single fluidised bed reactor concept with alternating dehydration-hydration processes, charging and discharging reactions, superheated steam as fluidisi...

To study the influence of impinging height H/D on flow field characteristics oblique submerged jets, numerical calculation an jet was carried out based Wray–Agarwal (W–A) turbulence model. The structure and pressure distribution under various heights (1 ≤ 8) when angle θ = 45° were analyzed. results show that with increase in height, diffusion degree gradually increased velocity decreased reach...
