Development of a Miniaturized Capillary Rheometer for High Shear Rate Rheology of Dense Suspensions
Advanced Materials Technologies, EarlyView.This research presents a downscaled benchtop, low‐cost capillary rheometer that can characterize high shear rate rheometry of dense suspensions. The device is capable of measuring across a wide range of applicable shear rates using only a limited quantity of material and addresses a need for an accurate and affordable capillary rheometer.

, 1982 A solar engine is disclosed in which a fluid, which is first heated and then cooled, forces a piston outward as the fluid is heated, and then draws the piston inward as the fluid is cooled. The piston is connected to a shaft and produces work as it moves

Journal of the Society of Mechanical Engineers, 1926 "In internal combustion engines, steam engines, air compressors, and so forth, the piston ring plays an important role. Especially, the recent development of Diesel engines which require a high compression pressure for their working, makes, nowadays, the packing action of the piston ring far more important than ever. Though a number of papers have been

Multiphase Flow Simulation of Blow-by and Fuel-in-Oil Dilution via the Piston Ring Pack Using the CFD Level-Set Method [PDF]
Modern diesel engines temporarily use a very late post-injection in the combustion cycle to either generate heat for a diesel particulate filter regeneration or purge a lean NOx trap. In some configurations, unburned fuel is left at the cylinder walls and is transported via the piston rings toward the lower crankcase region, where fuel may dilute the ...

Measure solutions to piston problem for compressible fluid flow of generalized chaplygin gas [PDF]
arXiv, 2022 We study the piston problem of the compressible fluid flow with the generalized Chaplygin gas. Depending on the inferential critical value of Mach number, we prove that, there exists an integral weak solution for the proceeding piston problem, consisting of a shock separating constant states ahead of the piston if Mach numbers less than this critical ...

Improved Direct Ink Writing of Liquid Metal Foams via Liquid Additives
Advanced Electronic Materials, EarlyView.The ability to pattern liquid metal is useful for making soft electrical and thermal devices. Dispensing liquid metal from a nozzle naturally results in the formation of spheroidal droplets, making direct‐write printing challenging. Liquid metal foams containing pockets of air can extrude as filaments, albeit inconsistently.
