An experimental study was performed to investigate the combustion instability characteristics of swirl-stabilized combustors. A premixed gas composed ethylene and air burned under various flow geometric conditions. Experiments were conducted by changing inlet mean velocity, equivalence ratio, swirler vane angle, combustor length. Two dynamic pressure sensors, a hot-wire anemometer, photomultipl...

Abstract. This paper describes the development of a theoretical model for turbulence spectrum measured by short-range, continuous-wave lidar (light detection and ranging). The performance was assessed measurements conducted with two WindScanners in an open-jet wind tunnel equipped active grid, range different turbulent conditions. A hot-wire anemometer is used as reference to assess lidar's sta...

Blood velocity measurements were carried out using a constant-temperature hot-film anemometer system in both anesthetized and conscious horses. Catheter probes were used to measure velocity wave forms in conscious horses and L-shaped needle probes inserted by direct vessel puncture were used to measure the profiles in regions of the thoracic and abdominal aorta of anesthetized, open-chest horse...

There is a growing interest in atomic layer deposition (ALD) of metals for ultra-large-scale integrated circuit (ULSIC) manufacturing. Radical-enhanced ALD (REALD) utilizing plasma (PEALD) has been proposed to grow a number of metals [1]. In our work, we investigate an alternative approach to REALD without plasma, i.e. replacing plasma by a hot (up to 2000 oC) tungsten (W) wire. In this so-call...

This paper describes the main principles of constructing innovative MEMS flow meters for gaseous working fluids. MEMS flow meter contains hot-wire thermoanemometrisc sensor which response to the temperature change caused by convective working fluid heat transfer from a hot-wire. The advantages of using hot-wire thermoanemometric sensors were analyzed. The main emphasis of this work is on speed,...
