Investigation of Pressure Transducer Adapter Dynamics
نویسنده
چکیده
A widely-used technique for reciprocating compressnr research is to use miniature pressure transQucers to measure cylinder pressure. A great deal of useful information on cylinder processes can be obtaine·· "!J this manner, providing that the information is accurate. These transducers must often be mounted outside the cylinder, in adapters, due to space constraints and interfering structures (such as va~v·c or the crankcase), It is an established fact that the internal passages and volumes of an adapter affect the pressure signal; thus, it is imperative that the characteristics o~ each adapter system b~ known in order t. prevent improper interpretatior, of the data. This report discusses pressure transducer-adapter systems, includes recommendat 1 .>m for design, and describes procedures for testin~ them.

An Investigation on the Effects of Gas Pressure Drop in Heat Exchangers on Dynamics of a Free Piston Stirling Engine
This paper is devoted to study the effects of pressure drop in heat exchangers on the dynamics of a free piston Stirling engine. First, the dynamic equations governing the pistons as well as the gas pressure equations for hot and cold spaces of the engine are extracted. Then, by substituting the obtained pressure equations into the dynamic relationships the final nonlinear dynamic equations gov...

Background: Direct monitoring of arterial pressure using a transducer system is not affordable in most operating rooms and ICU wards in Iran. It is, however, possible to use an aneroid manometer instead, but it is not standardized yet, nor studied enough and its measurements may not be interpretable. Methods: To study the correlation of the arterial pressure readings between a manometer and a ...
متن کاملCFD Simulations of Pressure Drop in KATAPAK-S Structured Packing
KATAPAK-S is a type of structured catalytic packing, which is used in reactive distillation processes. The dry pressure drop characteristic (the pressure drop in the absence of liquid flow) is of significant importance for the investigation of process hydrodynamics. In this paper, the dry pressure drop within the catalyst packed channels of KATAPAK-S has been investigated using Computational Fl...
