turbocharging an engine boosts its power by increasing the amount of input air. this task is accomplished by using the exhaust gas to power a turbine which is engaged with a compressor. the variable geometry turbocharger, vgt is a unique turbocharger that the diffuser vane angle can be changed over a wide range of positions. the mathematics of turbomachinery flow analysis is intensive and uses ...

introduction: in order to determine the multidrug resistance (mdr) phenotype due to p-glycoprotein expression in haematological malignancies including acute myeloblastic leukemia (aml), a well-characterized p-gp expressing cell line was required to validate and standardize flow cytometric assays and to calibrate instruments. therefore, this resistant subline of k562 was established for the firs...

prediction of fluid-elastic instability is a great matter of importance in designing cross-flow tube bundles from the perspective of vibration. in the present paper, the threshold of fluid-elastic instability has been numerically predicted via simulation of incompressible, unsteady, and turbulent cross-flow through a tube bundle in a normal triangular arrangement. the conditions of simulation i...

Main contribution of this work is improving transient stability by installing Flexible AC Transmission System (FACTS) in power systems. For do this, Unified Power Flow Controller (UPFC) has been selected. Also a novel structure has been suggested to improve classic Harmony Search algorithm and suggested improved Harmony Search (iHS) algorithm. This algorithm has been used to obtain UPFC paramet...

Liquid film thickness measurements under temperature-varying conditions in a two-phase flow are of great importance to refining our understanding of two-phase flows. In order to overcome the limitations of the conventional electrical means of measuring the thickness of a liquid film, this study proposes a three-electrode conductance method, with the device fabricated on a flexible printed circu...

In this study, we report on a simple and versatile plug-n-play microfluidic system that is fabricated from flexible assembly of glass-based flow-control modules for flexibly manipulating flows for versatile emulsion generation. The microfluidic system consists of three basic functional units: a flow-control module, a positioning groove, and a connection fastener. The flow-control module that is...

background: urtica dioica is one of the medicinal herbs with many uses in treating various diseases. in some studies, its antiproliferative and apoptotic effects on cancer cell lines have been shown. therefore, the evaluation of u. dioica effect was performed on kg-1 cell line for acute myelogenous leukemia (aml) for the first time in this study. materials and methods: kg-1 cell line was treate...

Flexible barriers undergo large deformation to extend the impact duration, and thereby reduce the impact load of geophysical flows. The performance of flexible barriers remains a crucial challenge because there currently lacks a comprehensive criterion for estimating impact load. In this study, a series of centrifuge tests were carried out to investigate different geophysical flow types impacti...

temperature restrictions on aqueous effluents dictate that streams with a temperature higher than the permitted level needed to pass through cooling systems to reduce the effluent temperature before discharge. in this study, by considering the grouping design rules based on pinch technology, an optimum design for a distributed effluent cooling system, has been developed. a counter-flow wet cool...

Abstract In this work, the role of appropriate mixing for mercaptan removal from Kerosene using caustic soda has been investigated in the pilot scale. Static mixer at different condition has been used as a passive mixing tool to achieve proper mixing and consequently high performance of mercaptan removal. Two lengths of static mixer including 20 and 40 cm as well as two pitches 1 and 3 m...
