Abstract:
This paper considers a three-dimensional mathematical model of heat and mass transfer in an oil well with a bottom-hole heater. The vertical section of an oil well with an electric bottom-hole heater device for wells with highly viscous and paraffinic oil was investigated. The bottomhole heater is a monolithic cylinder located in the lower part of the tubing. The tubing contains perforations through which the oil fluid enters the tubing. The use of a local heater in the near-wellbore area makes it possible to increase the temperature of the fluid flowing through it, thereby reducing the viscos

Objective of this study is to experimentally investigate the effect of centrifugal accelerations on thermal resistance of the rotating closed-loop pulsating heat pipe (RCLPHP). The RCLPHPs were made of a copper tube with internal diameter of 1.50 and 1.78 mm and bent into flower’s petal-shape and arranged into a circle with 11 turns. The evaporator section located at the outer end of the bundle while the condenser section placed around the center of the RCLPHP with no adiabatic section. Both sections had an identical length of 50 mm. R123, and ethanol was filled as working fluid respectively.

Low-temperature energy systems are processes that operate below ambient temperatures and make use of refrigeration cycles, where the main energy consumption is due to the shaft work required to drive the compressors. Very-low-temperature energy systems, also known as cryogenic processes, operate at around -150°C and below. Due to increasing demand of products from cryogenic processes and tighter environmental regulations, existing plants need to be revamped to increase their energy efficiency or adapt to new processing capacities.

This is the first study to apply and validate DES to predict the internal flow and heat transfer in non-canonical flows of industrial relevance.

Abstract:
Increasing the turbine inlet temperature of gas turbine engines significantly increases their power output and efficiency, but it also increases the likelihood of thermal failure. Internal passages with tiny ribs are typically cast into turbine blades to cool them, and the ability to accurately predict the flow and heat transfer within these channels leads to higher design reliability and prevention of blade failure resulting from local thermal loading. Prediction of the flow through these channels is challenging, however, because the flow is highly turbulent and anisotropic, and the presenc

Abstract:
In this thesis, the ribbed ducts of the internal cooling passage in turbine blading are investigated to demonstrate the effects of high speed rotation. Rotation coupled with high temperature operating conditions alters the mean flow, turbulence, and heat transfer augmentation due to Coriolis and centrifugal buoyancy forces that arises from density stratification in the domain. Gas turbine engines operate in particle laden environments (sand, volcanic ash), and particulate matter ingested by the engine can make their way into the blade internal cooling passages over thousands of operating hours

Abstract:
Abstract Conventionally solid corrosion resistant seamless pipes are made by hot forming process. This is subsequently followed by final finishing in terms of heat treatment and non-destructive inspection. An alternative process for the manufacture of seamless pipes is the horizontal spun casting process. In this process the mould is spinning during solidification. Centrifugal forces result in the formation of a dense casting. This process allows pipes to be manufactured on a customized basis like diameter, wall thickness and alloy composition. In terms of usage of solid corrosion resistant al

Abstract:
Abstract This paper discusses a test program to in-situ evaluate the comparative performance of six centrifugally cast heater tube alloys in an ethylene pyrolysis heater. The unusually high creep growth of conventional HP-40 radiant tubes leading to development of the test program is described, as well as the performance of the test tubes, as measured by post exposure creep growth, carburization behavior, microstructural analysis and time to failure. The performance of an aluminized tube in a separate pyrolysis heater is also described.

Abstract:
This project considers some of the geotechnical and geothermal engineering issues that will need to be considered for the design and construction of large diameter gas transmission pipelines from the arctic production areas to southern markets. The challenges relate to determination of the frost heave and thaw settlement behaviour of a pipeline as it crosses from areas of continuous permafrost, through discontinuous zones to completely unfrozen ground conditions. The use of chilled gas will overcome some problems in already frozen ground but will cause frost heave where a frost bulb is formed

Abstract:
The reliance on centrifugal pumps the world over implies a heavy reliance on mechanical seals. In order to get the highest level of performance from the seals, auxiliary systems are used either to condition the seal operating environment or monitor the systems and detect failures. Current standards already exist that recommend seal auxiliary systems based on certain pump operating conditions, and are widely accepted in the industry both among seal end-users and vendors. And because of their knowledge on the actual seals, the vendors are the primary source for end-users to receive designs and e
