Comparison of hot wire/laser velocimeter turbulence intensity measurements [PDF]
The question of whether a random measure of particle velocities yields a good statistical estimate of the stationary condition of the turbulence flow field was investigated by comparing hot-wire and laser velocimeter turbulence intensity measurements ...

Plasmon-pole approximation for semiconductor quantum wire electrons
, 1996 We develop the plasmon-pole approximation for an interacting electron gas confined in a semiconductor quantum wire. We argue that the plasmon-pole approximation becomes a more accurate approach in quantum wire systems than in higher dimensional systems ...

Hot Wire Liquid-Level Indicator [PDF]
Review of Scientific Instruments, 1956 The theory of the method of measurement of liquid level by measurement of the resistance of a heated wire is developed, and it is applied to the design of a liquid-nitrogen-level indicator having a power dissipation of 3.4 mw/in. of length and a deviation from linearity in the calibration of less than 0.1 in. over its working length of 2.0 in.

A suggested method for measuring turbulence [PDF]
The desirability of a quantitative measure of turbulence is emphasized, and a possible method of attack on the problem is discussed. Data are presented to show that the hot-wire anemometer has possibilities as an instrument for measuring turbulence.

Hydrothermal Surface-Wave Instability and the Kuramoto-Sivashinsky Equation
, 1994 We consider a system formed by an infinite viscous liquid layer with a constant horizontal temperature gradient, and a basic nonlinear bulk velocity profile.

Novel hot-wire based spirometry is highly accurate at low flow rates
Current Directions in Biomedical Engineering, 2018 Spirometry is the most commonly used pulmonary function test. The aim of this comparative study was to evaluate four commercially available spirometers with different measurement principles (turbine-, ultrasound-, differential pressure- and hot-wire ...

DNS of a hot-wire anemometer in a turbulent channel flow [PDF]
, 2014 A body with a shape similar to a hot wire with its sheath, but no prongs, has been placed close to the wall of a turbulent channel at Re_tau = 600. The results of the channel flow, without the wire, agree with previous published ones, despite the modest ...
