High pressure and high temperature acoustic sensor

The Journal of the Acoustical Society of America, 2009
An acoustic sensor, such as a hydrophone, is deployable in a fluidic media having high temperature, high pressure, and/or potentially caustic chemicals. The hydrophone includes a housing filled with an internal fluid and containing a sensing mandrel. The sensing mandrel senses the acoustic pressure transmitted to the internal fluid through a diaphragm.

Critical temperatures and pressures and high temperature vapour pressures of seven alcohols

Chemical Engineering & Technology, 1990
AbstractCritical temperatures and pressures have been determined experimentally for the four lowest n‐alcohols, 2‐propanol, 2‐butanol, and 2‐methyl‐1‐propanol, and are given in the penultimate line of Table 3. The last line of Table 3 lists the weighted mean critical pressures, with the corresponding critical temperatures obtained from he vapour ...

Flame Temperature Calculations at High Temperature and Pressure

Propellants, Explosives, Pyrotechnics, 1994
AbstractIn the past, real gas effects on the flame temperature were evaluated using the virial equation of state. Usually, the virial expansion was truncated after the third term. In this work the equation of state for dense gases proposed by Haar and Shenker is considered.

High-temperature pressure and temperature multi-function sensors

1998 5th International Conference on Solid-State and Integrated Circuit Technology. Proceedings (Cat. No.98EX105), 2002
High-temperature pressure and temperature multi-function sensors have been fabricated using polysilicon as piezoresistor and silver resistors as thermometer. The polysilicon SOI structure is able to operate at high temperature. Over the range of room temperature to 350/spl deg/C, the pressure and temperature properties of the sensors have been measured.

Rheology at High Pressures and High Temperatures

2010
We review recent progress in studying deformation at simultaneous high pressure and high temperature using in-situ diffraction and imaging in the large volume press (LVP). Current state-of-the-art deformation devices and diffraction and imaging techniques are introduced, along with theoretical background for stress measurements based on diffraction ...

Design optimization of high pressure and high temperature piezoresistive pressure sensor for high sensitivity

Review of Scientific Instruments, 2014
This paper describes a design method for optimizing sensitivity of piezoresistive pressure sensor in high-pressure and high-temperature environment. In order to prove the method, a piezoresistive pressure sensor (HPTSS) is designed. With the purpose of increasing sensitivity and to improve the measurement range, the piezoresistive sensor adopts ...

Rubidium at high pressure and temperature

Journal of Physics: Condensed Matter, 2000
In the present paper we report theoretical calculations for the Hugoniot of shock-compressed rubidium. We use an all-electron full-potential method based on density-functional theory to obtain the total energy, pressure and electronic density of states.

High-Temperature and High-Pressure Steam Lines

Transactions of the American Society of Mechanical Engineers, 1922
Abstract The pronounced tendency of modern power-plant designers to use high superheat and high pressure, as well as the recent extensive use of highly superheated steam in process work, lead the author to make a review of the available data and formulas on radiation and friction losses in pipe lines. All tests to determine the radiation
