..., respectively. The power density of the proposed injector-pumped design is seen to behave like that of turbopumped microrockets up to a critical nozzle throat diameter of approximately 1 cm, beyond which the advantages of an entirely static structure are outweighed by decreasing performance.

... impingement. In order to make comparisons with a previous single jet study by the authors, each impinging jet within the array was geometrically constrained to a round, 8.5 mm diameter, square-edged nozzle at a jet exit-to-target surface spacing, of H / D = 0.5 . A custom measurement facility was designed...

... effect on the simulated temperature distribution. As the calcining kiln rotates, the tertiary air injection nozzles will move relative to the coke bed and exert cyclic air-bed interactions. At zero angular position, the air injection nozzles are diametrically located away from the bed so the interactions...

... to study the flow and temperature fields in the vicinity of the injector tip and the metal temperature of two different fuel injector designs—one with a conical-nozzle tip and the other with a blunt tip—in a dry-fed, entrained-flow coal gasifier. The complete 3D Navier–Stokes equations are solved...
