For an isolated flute head joint, the effects of jet angle on harmonic structure a single note are investigated within practical range for human players. The mechanisms these discussed basis both radiated sound and flow field measured with hot-wire anemometer. blowing parameters, viz., (angle between direction window), offset (relative height from edge), lip-to-edge distance, rate, were varied ...

background: in intracavitary brachytherapy for gynecological cancers, various techniques are used to locate the anterior rectal wall nearest to the sources but there is no consensus on the best method to do so. this study aimed to compare a technique used routinely in some centers that employs a wire marker to locate the position of the maximum rectal dose point, versus the method recommended b...

This study investigates the influence of side wind flowing directly from different indoor environments on airflow laboratory fume hood (LFH). When an LFH is used to discharge harmful laboratory, can affect LFH, which likely cause leakage fumes. In this study, incense was simulate fumes, sampling and analysis total suspended particulate concentrations were performed in under conditions with or w...

Vortex generators are devices that modify the wind behavior near surface of turbine blades. Their use allows boundary layer shedding transition zone to be varied. Bio-inspired design has been used improve efficiency aerodynamic and hydrodynamic systems by creating shapes present in animals plants. In this work, an experimental methodology is proposed study effect bio-inspired vortex their on st...

ABSTRACT This study presents a numerical and experimental comparison of two different types radial fans used in an agricultural fertilizer spreader at rotation 4000 rpm. The analysis was validated through experiments conducted on test bench using hot-wire anemometer for velocity measurements Pitot tube pressure readings. A simulation the carried out after validation mathematical models to evalu...

Thermal comfort in spaces can be defined as the creation of conditions that will provide users’ living standards. Therefore, it is important to investigate thermal different types dwellings and design parameters affect these conditions. In this study, were investigated. context, measured between December 2020 January 2022 four selected Bingöl, located a cold climate. Measurements made daylight ...

It is a relevant objective in thermal physics and building reciprocating internal combustion engines (RICE) to obtain new information about the thermal-mechanical characteristics of both stationary pulsating gas-flows complex gas-dynamic system. The article discusses physical features gas dynamics heat transfer flows along length system typical for RICE exhaust systems. Both an experimental set...

Conical diffusers of various configurations are used in many kinds technical equipment and manufacturing processes. Therefore, it is a relevant objective to obtain reliable experimental mathematical data on the aerodynamic characteristics diffusers. This article presents aerodynamics stationary flows vertical conical diffuser when air supplied through tubes with cross sections (circle, square, ...
