A thermosyphon is a gravity-assisted heat pipe used to improve the heat transfer in several applications. In this paper, a thermal analysis of a finned thermosyphon for heat exchanger applications was experimentally researched. The thermosyphon was manufactured from a copper tube the external diameter of 9.45 mm, the inner diameter of 7.75 mm, and a total length of 200 mm. The working fluid used was water with a filling ratio of 40% of the evaporator volume. The condenser was cooled by air...

As devices shrink, the current density through interconnects increases proportionally making new materials a necessity for industry growth. Carbon nanofiber (CNF) and carbon nanotube's (CNT) potential for high current density make them a possible replacement for metal contacts. Learning the limitations of CNFs and CNTs is important if they are to be used in next-generation electronics. As current density increases, heat is generated throughout the CNF structure. This heating eventually leads to...

The Naval Post Graduate School has obtained software which can be used for the thermal analysis of an electronic component. This software includes two versions, one for steady state analysis and the other for transient analysis. Each version consists of two programs, a model builder and a thermal analyzer. This thesis describes a user friendly, menu driven specific model builder which may be used to rapidly generate a thermal model, containing up to 750 nodes, for a microcircuit die. This model...

The aim of this research work is to thermally analyze Al6061 alloy friction stir welding (FSW) using numerical and experimental methods. The I nfrared (IR) thermometer was used to measure the temperature profile during FSW at various locations of the specimen in the FSW direction. Three-dimensional finite element models were used to investigate the thermal profile in the welding of Al alloy and the heat sources generated due to the friction reaction between the tool shoulder and welded...

Sodium selenate is an important inorganic compound but lacks reliable and accurate physico-chemical and spectral characterization information. The study was carried out for the in-depth physicochemical, thermal, and spectroscopic characterization of sodium selenate using various analytical techniques. The powder X-ray diffraction spectroscopy analysis showed well-defined and sharp peaks indicated sodium selenate is crystalline in nature. The crystallite size was found to be in the range of...

Cooling of gas turbine blades are major attention to high temperature working conditions. Numerous methods have been recommended for the cooling of blades and a unique technique is to be used to ensure radial holes to pass high velocity cooling air along the blade span. The forced convection heat transfer from the blade to the cooling air, it will reduce the temperature of the blade to permissible limits. Finite element analysis is used in the present work to examine steady state thermal andamp...

Batch mode experiments of dyes adsorption were performed and the effects of various parameters such as contact time, adsorbent dosage, initial dye concentration, pH and temperature were examined. Successively, the dyes have been desorbed from the adsorbent and were recycled to dye a cotton fabric. The maximum efficiencies in dye removal, performed...

Soil warming can increase soil organic carbon (SOC) mineralization, triggering a positive climate‑carbon cycle feedback loop. Globally, many soil warming experiments have examined losses of bulk SOC, but few have assessed changes in quality. Accurate knowledge of the latter is required for an in-depth understanding and improved prediction of SOC feedback to climate change. In this study, we used Rock-Eval thermal analysis (RE6) to characterize shifts in SOC thermal stability and bulk...

Abstract — Eugene Island (EI) 276 fields presents an interesting case study of overpressure caused by uncompacted porosity, in addition to heat. Mechanics of sand deposition, transgressive shale, surrounding faults, overlying shale barriers and underlying salt diapirs have caused temperature anomalies in the P1-sand. Plio-Pleistocene sandstone reservoirs are supplied with mature hydrocarbons by migration of fluids from overpressured shales upwards along an active fault system. The heat...

Quantum calorimeters are being developed as imaging spectrometers for future X-ray astrophysics observatories. Much of the science to be done by these instruments could benefit greatly from larger focal-plane coverage of the detector (without increasing pixel size). An order of magnitude more area will greatly increase the science throughput of these future instruments. One of the main deterrents to achieving this goal is the complexity of the readout schemes involved. We have devised a way to...

After a cryogenic liquid has been liquefied and purified to the desired level it should then be put away and transported. Cryogenic fluid storage-vessel and transfer line design has progressed rapidly as a result of the growing use of cryogenic liquids in many areas of engineering and science. The development of the Dewar vessel represented such an improvement in cryogenic fluid storage vessels that it could be classed as "break-through" in container design. Cryogenic Pressure vessels...

We reexamine both numerically and analytically the collapse of the singular isothermal sphere in the context of low-mass star formation. We consider the case where the onset of collapse is initiated by some arbitrary process which is accompanied by a central output of either heat or kinetic energy. We find two classes of numerical solutions describing this manner of collapse. The first approaches in time the expansion wave solution of Shu, while the second class is characterized by an...
