TL;DR: In this paper, the effects of particle size, solid inventory and operating pressure on bed hydrodynamics and heat transfer in a pressurized circulating fluidized bed has been studied.

TL;DR: In this paper, the authors explored the influence of emulsified palm biodiesel as a pilot fuel in a biogas run dual fuel engine and found that with the presence of a microexplosion, emulsification of biodiesel can increase the magnitude of the peak cylinder pressure (PCP) which increases the expansion ratio and hence improves engine efficiency.

TL;DR: The blade profiles and blade shapes of vertical-axis Savonius wind turbine rotors have undergone a series of changes over the past three decades as mentioned in this paper, and there is not a single piece of literature that gives a comprehensive and a systematic review of rotor blade profile and shape.

TL;DR: In this paper, a vent-augmented elliptical-bladed Savonius rotor with a newly developed blade profile and an augmentation technique have been combined, and the results obtained are compared with those of non-vented and semicircular profiles.

TL;DR: In this paper, the authors proposed an inverse methodology aided by the DE algorithm to simultaneously estimate and optimize geometric parameters of a semicircular-bladed Savonius Style wind turbine.
