The Geometrical Optimization of MSFL Pad Design by COMSOL Multiphysics® and Design of Experiments

T. Hao[1], J. M. Singer[1]
[1]GE Oil & Gas, Farnborough, UK

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 ... Mehr lesen

We present quantitative nano-scale analysis of the 3D spatial structure of an anticorrosive aluminium epoxy barrier marine coating obtained by ptychographic X-ray computed tomography (PXCT) [1-3]. We then use COMSOL Multiphysics® software to perform simulations on the acquired real 3D ... Mehr lesen

Baffle Design: Tube-in-Shell Electrical Gas Heaters

K. Lund[1], S. Lord[2]
[1]Kurt Lund Consulting, San Diego, CA, USA
[2]SML Associates, Encinitas, CA, USA

It is frequently necessary to electrically heat gases; a convenient geometry is the familiar tube-in-shell heat exchanger, where the tube side is modified for electrical heater-rods, and the baffled shell side contains the flowing gas, as indicated in Fig. 1. However, this modification ... Mehr lesen

Influence of Axial Conduction in the Design of a Compact Recuperator for Catalytic Combustor Based Portable Power Generation

A. N. Smith[1], H. Nochetto[2], C. M. Waits[2]
[1]U.S. Naval Academy, Annapolis, MD, USA
[2]U.S. Army Research Lab, Adelphi, MD, USA

Catalytic micro-combustor represents an exciting area of research for portable power generation. Extensive research is being currently conducted on the design of the reactor and catalyst selection [1]. However another critical element of the design will be a recuperator to minimize ... Mehr lesen

Temperature and Acceleration Sensitivities of a Dual Cavity Fabry-Perot Interferometer

[1]R. K. Banyal
Indian Institute of Astrophysics, Bengaluru, Karnataka, India[1]

The numerical study of temperature and acceleration sensitivities of a dual cavity Fabry-Perot (FP) interferometer is carried out using finite element method. The optical cavities are formed by machining two side-by-side circular bore of 12 mm each on a monolithic block of low expansion ... Mehr lesen

Simulation of the Temperature Profile During Welding with COMSOL Multiphysics® Software Using Rosenthal's Approach

A. Lecoanet[1], D. G. Ivey[1], H. Henein[1]
[1]Department of Chemical & Materials Engineering, University of Alberta, Edmonton, AB, Canada

A 3D finite element analysis is carried out, using COMSOL® software, to reproduce the thermal profile obtained with Rosenthal’s equation. The implemented heat transfer equation has been modified as a means to approximate Rosenthal’s solution. An analysis of the differences between the ... Mehr lesen
