hydrochlorothiazide detection in urine samples by hplc-dad and experimental design dispersive l-l microextraction

hydrochlorothiazide (hct) is a diuretic agent which is shown to be effective in the treatment of hypertension. literature reports have demonstrated that urinary excretion data may be used to assess the bioavailability of various formulations containing this thiazide. also hct consumption by the athletes is one of the drugs which should be regulated by world anti-doping agency (wada), because of...

Design, Analysis and Fabrication of a Meso-scale Centrifugal Compressor

A gas or vapor compressor is one of the key components of many engineering systems, such as certain designs of vapor compression refrigeration systems, cryo-coolers, air handlers. For meso-scale systems with linear dimensions of a few centimeters, conventional designs do not work efficiently because of rather large relative tolerances, and hence these meso-scale systems require micro-fabricated...

CFD Analysis of Off-design Centrifugal Compressor Operation and Performance

This paper presents some of the results from a Master’s thesis research into the performance and operation of a centrifugal compressor at off-design operating conditions using advanced computational fluid dynamics (CFD) techniques. ANSYS CFX is the CFD solver used in this blind study to evaluate the ability of modern CFD software to predict the performance of centrifugal compressors operating a...

Effects of Impeller Gap on Rotor Vibration in a High Speed Centrifugal Compressor: A Numerical and Experimental Analysis (TECHNICAL NOTE)

Centrifugal compressors produce high pressure ratio and rotate at speeds. So, a tiny unbalance can produce severe vibration. In this paper, effects of impeller gap on rotor vibration in a high speed centrifugal compressor is investigated. For this purpose, a numerical and experimental analysis are carried out. The moving reference frame method in FLUENT software is used for modeling of geometri...
