Orifice of Return
Orifice of Return is a collection of poetry that posits Black femme bodies as living and breathing archives, corporeal manifestations of intuitive and intellectual claims at survival. The poems in this collection illustrate the multifaceted nature of my craft, through which the personal, the …

Experimental investigation of cavitation in a cylindrical orifice
… While, the presence of cavitation in plain orifice atomisers is known to enhance this process, the complex flow mechanisms that result within the nozzle, such as periodic cavitation shedding, are not fully understood. A new cavitation research rig was designed and built to investigate the …

A study of tip-leakage flow through orifice investigations
… fluid dynamics of flow through plain-faced long orifices was investigated with the hope of gaining insight into the fluid dynamics of tip leakage flow. The Reynolds number range investigated was greater than 10*. Measurements were made of the discharge coefficient as a function of back pressure …

Computer aided mathematical modelling of turbulent flow for orifice metering
… high Reynolds number turbulence through an orifice plate. The model developed for orifice plates was based on a particular closed form turbulent model: the k-ε two equation model developed at Imperial College, London and embodied in the TEACH-T finite difference computer code. A basic model …

Calibration of orifice plates with special emphasis on edge sharpness and eccentricity
… literature pertaining to flov1 measurement with orifice plates is presented. Special emphasis is laid on the factors influencing the coefficient of discharge Of orifice plates and. on the difference between the various engineering standards. Particular consideration is given to the effect on the …

Experimental study and characterization of bubble behaviors in the orifice-induced hydrodynamic cavitation
… to characterize the development process of orifice-induced cavitation and transitional bubble behaviors. The transition from non-cavitation to fully developed cavitation was carefully studied. Cavitation bubble clouds were observed at orifice, indicating the inception of cavitation. The …

Design of a single orifice pulse tube refrigerator through the development of a first-order model
A first order model for the behavior of a linear orifice pulse tube refrigerator (OPTR) was developed as a design tool for construction of actual OPTRs. The model predicts cooling power as well as the pressure/volume relationships for various segments of the refrigerator with minimal computational …

Spray visualization and characterization of a multi variable circular orifice (MVCO) injector coupled with a swirl adapter for diesel reformer applications
… characterization of a Micro-Variable Circular-Orifice (MVCO) fuel injector coupled with a swirl-producing adapter was studied. The spray characteristics such as spray penetration length, spray velocity etc. and the atomization performance were evaluated. The measurement was conducted on an …

Positive pressure drop-on-demand printhead for Three-Dimensional Printing
… wetting out of the binder fluid onto the orifice face typically has been prevented by some combination of the following: coatings on the orifice face, high surface energy fluids, and negative pressure. This non-wetting approach is not practical for low surface energy fluids. A new positive …

A mathematical model of transient flow in pipeline filling
… was assumed to be horizontal and to contain an orifice at the downstream end. The key elements of the model were the momentum equation governing the flow of the water, the thermodynamic equations for the compression and discharge of the entrapped air, and the equations for waterhammer resulting …

Direct numerical investigation and reduced-order modeling of 3-D honeycomb acoustic liners
… development. While there are numerous orifices and cavities in a general conventional acoustic liner sample, only the one orifice and one cavity is investigated in this work. Resolved simulations of the sound-induced flow through a circular orifice with a 0.99 mm diameter are examined. …

Realistic modelling of leakage in water distribution pipe networks
… Introducing this linear relationship into the orifice equation, results in a two-part modified orifice equation for leakage modelling with pressure head exponents of 0.5 and 1.5 respectively. Current hydraulic network solvers apply the conventional power leakage equation to model pressure …

Application of a Helmholtz resonator excited by grazing flow for manipulation of a turbulent boundary layer.
… study of the resonator showed that when the orifice length is increased the pressure fluctuations within the resonator are reduced, potentially due to the larger skin friction inside the orifice. To understand the boundary layer features over a flow-excited Helmholtz resonator a Large Eddy …
