The evaluation of defect size and nature are two most controversial topics in ultrasonic flaw detection. The operation consists of an application of ultrasonic waves to pipes in order to detect metal loss and other defects in the pipe wall due to corrosion and other degradation ... Per saperne di più
Logging-while-drilling (LWD) acoustic transducers provide real-time data about the geologic and geophysical properties of the borehole that ensure safety margins and optimize completion. It is important to understand what causes the different resonance modes in the transmitter and obtain ... Per saperne di più
Introduction Micro-Spherically Focused Logging (MSFL) tool is a microresistivity open-hole logging tool designed to measure the resistivity of the flushed zone, a region of formation close to the borehole, independent of any mudcake on the borehole wall. Original designs of MSFL were ... Per saperne di più
A comparison of discrete fracture and explicit fracture models for single-phase flow in fractured porous media using COMSOL Multiphysics® software is presented to understand the contribution of each individual fracture to fluid flow, and the exchange between fracture and surrounding ...

THM (Thermo-Hydro-Mechanical) behavior of the reservoir during SAGD (Steam-Assistant-Gravity-Drainage) was studied through a proper constitutive modeling of the porous media. Specifically, a generalized density-stress-fabric dependent elasto-plastic model with stress-dilatancy and ... Per saperne di più
Introduction The COMSOL Multiphysics® software and its CFD Module have a physics interface for solving Laminar Two-Phase Flow problems using the Level Set method (1). This paper discusses how the tool may be used with more than two phases when the flow is laminar. It then introduces a ... Per saperne di più
Magnetorheological Finishing (MRF) is one of the precision finishing processes in which magnetic field is used to drive abrading forces for Finishing 2D and complex 3D surfaces. In this paper, Ball End Magnetorheological Finishing (BEMRF) has been analyzed for fluid behaviors under the ... Per saperne di più
Due to the advantages of induction heating as a method for precise and efficient local heating, it is perfectly suited for thermal shrink fitting of a gear wheel on a shaft. In this work, a simulation model was established to study the induction heating of a gear wheel, its thermal ... Per saperne di più
Fluidized Catalytic Cracking (FCC) regenerators utilize a fluidized bed to facilitate catalyst regeneration. Cyclones are used to separate the catalyst from the gas stream and return the catalyst to the fluidized bed; as the gas progresses through the system for further processing. This ...

This paper presents a simulation approach to develop a model for understanding the mixing phenomenon in a stirred vessel. The mixing in the vessel is important for effective chemical reaction, heat transfer, mass transfer and phase homogeneity. In some cases, it is very difficult to ... Per saperne di più
