Present study reports a computational investigation on heat transfer and pressure drop characteristics for flow through exchanger tube fitted with novel hybrid ribs by using magnetic nanofluid (Fe 3 O 4 ). Effects of different rib geometry have been investigated Reynolds number ranging from 000 to 22 000. Until now, there is little information available in the literature method quantifying effe...

Pre-commissioning and periodic in-service visual inspection of reactor vessel internals, of Prototype Fast Breeder Reactor (PFBR), is a mandatory regulatory requirement. An Indigenous Instrument (Periscope) is designed for this purpose. The instrument is accommodated within a tube of 400 mm outer diameter and has a length of 10 meters. The single tube contains viewing, illumination and the asso...

In the past few decades, water and air were commonly used as working fluid to evaluate shell tube heat exchanger (STHE) performance. This study was undertaken estimate transfer coefficients performance in pilot-scale twisted tube-based STHE using flue gas from biomass co-combustion fluid. Theoretical calculation along with experimental results calculate specific of gas. A simplified model then ...

The employment of atmospheric pressure plasma jets (APPJs) in a large sort applications is limited by the adversities related to size treated area and difficulty reach target. use devices that employ long tubes their structure has contributed significantly overcome these challenges. In this work, two different systems employing jet transfer technique are compared. main difference between how pl...

nowadays, tube bonding in vehicles structure is noticeably considered by many researches. in this paper, local tube compression process by a rubber ring has been studied. firstly, simulation of the process was performed by fem. then, experimental test has been carried out to validate the numerical results. numerical and experimental results were compared showing a good agreement. in the second ...

Nanofluids are generally utilized in providing cooling, lubrication phenomenon, and controlling the thermophysical properties of working fluid. In this paper, nanoparticles Al2O3 added to base fluid, which flows through counterflow arrangement a turbulent flow condition. The fluids employed ethylbenzene water, have differing velocities on both tube shell side cylinders. A tube-type heat exchang...

chest tube (ct) or tube thoracostomy placement is often indicated following traumatic injuries. premature movement of the chest tube leads to increased hospital complications and costs for patients. placement of a chest tube is indicated in drainage of blood, bile, pus, drain air, and other fluids. although there is a general agreement for the placement of a chest tube, there is little consensu...

Much of the discussion in the public domain relating to shockwave interaction with flames, and the use of high explosives to extinguish, for instance, oil and gas well fires, is anecdotal and outside of scientific literature. The result is a lack of consistent insight into the physical mechanisms involved. It has been proposed by several researchers that the shock waves and the strong vortex ri...
