Experimentally Based Numerical Simulation of the Influence of the Agricultural Subsurface Drainage Pipe Geometric Structure on Drainage Flow

open access: yesAgriculture, 2022
The geometric structure of corrugated plastic pipes affects performance in agricultural subsurface drainage systems. To explore the influence of pipe geometry on flow field characteristics and the characterization of water movements, we developed a three-

Constant Rate of Momentum Change Ejector: simulation, experiments and flow visualisation [PDF]

open access: yes, 2017
An ejector is a momentum-transfer device that requires no external mechanical input or moving parts. However, ejectors have low performance due to irreversibilities such as viscous losses and shocks in the primary stream and diffuser.

Flow Continuity of Infusion Systems at Low Flow Rates [PDF]

open access: yesAnaesthesia and Intensive Care, 1995
Infusion of fluids and drugs at very low rates may be necessary in neonatal intensive care. Marked haemodynamic fluctuations occurring during the infusion of inotropes have been shown to be due to the sticking of the plunger in the barrel of syringes used in syringe drivers.

The Effect of using different Nano fluids on Heat Transfers through Flat Plate Solar Collector

open access: yesWasit Journal of Engineering Sciences, 2018
In this paper investigation experimentally the effect of CuO-water and Al2O3/water nanofluids on heat transfer in flat plate solar collector. The volume fraction was used (0.125,0.25 and 0.5) % for flow flow rate of working fluid equal to (1 L/min) and ...

An investigation of customer order flow in the foreign exchange market [PDF]

open access: yes, 2009
This paper examines the effect that heterogeneous customer orders flows have on exchange rates by using a new, and the largest, proprietary dataset of weekly net order flow segmented by customer type across nine of the most liquid currency pairs. We make
