Role of impinging jets in the biomechanical correction of the intraocular pressure ( IOP ) measurement [PDF]

open access: yes, 2018
Glaucoma is one of the ocular diseases which develops when the eye internal fluid cannot drain properly and intraocular pressure builds up. This can result in damage to the optic nerve and the nerve fibers from the retina and early diagnosis is very ...

Application of a pressure based CFD code with mass transfer model based on the Rayleigh equation for the numerical simulation of the cavitating flow around a hydrofoil with circular leading edge

open access: yesEPJ Web of Conferences, 2014
The most common method for simulating cavitating flows is using the governing flow equations in a form with a variable density and treats both phases as incompressible in combination with a transport equation for the vapour volume fraction. This approach

Optimization of the impeller for hydraulic performance improvement of a high-speed magnetic drive pump

open access: yesAdvances in Mechanical Engineering, 2022
Magnetic drive centrifugal pumps have compact structure and lower efficiency than ordinary centrifugal pumps. The surrogate-based optimization technique was applied to improve the performance of a high-speed magnetic drive pump with the help of numerical

Experimental Study on Unsteady Cavitating Flow and Its Instability in Liquid Rocket Engine Inducer

open access: yesJournal of Marine Science and Engineering, 2022
To study instability in the unsteady cavitating flow in a liquid rocket engine inducer, visualization experiments of non-cavitating and cavitating flows inside a model inducer were carried out at different flow conditions. Visual experiments were carried
