Different facilities for hadrontherapy have been built in the recent past. AISHa ion source has been designed by keeping in mind the typical requirements of hospital-based facilities, where the minimization of the mean time between failures (MTBF) is a key point together with the ... 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

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

Analysis of 3-D Printed Structural Components for Cube Satellites

C. Herzfeld[1]
[1]SPAWAR Systems Center (SSC) ATLANTIC, Charleston, SC, USA

Additive manufacturing uses 3D printing to build physical parts from CAD-based designs. The technology includes fused deposition modeling (FDM) and selective laser sintering (SLS) methods. 3-D printing is of particular interest for smaller, one-of-a-kind, customizable products. A cube ... Mehr lesen

Understanding Logging-While-Drilling Transducers with COMSOL Multiphysics® Software

[1]Department of Electrical Engineering, Materials Research Institute, Pennsylvania State University, University Park, PA, USA
[2]Department of Technical Services, China Oilfield Services Limited, Yanshan, Hebei, China

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 ... Mehr lesen

An Approach to Modeling Vacuum Desorption

C. F. Gomez[1], R. Schunk[1], R. F. Coker[1], J. Knox[1]
[1]NASA Marshall Space Flight Center, Huntsville, AL, USA

The objective of this simulation effort is to develop a mathematical model of vacuum desorption on a POC (Proof of Concept) canister loaded with Zeolite 13X/5A . This canister contains a pelletized adsorption bed which is used to adsorb H2O and CO2. Once this bed is fully saturated with ... Mehr lesen

Updated Results of Singlet Oxygen Modeling Incorporating Local Vascular Diffusion for PDT

R. Penjweini[1], M. M. Kim[1], T. C. Zhu[1]
[1]Department of Radiation Oncology, University of Pennsylvania, Philadelphia, PA, USA

Introduction: Singlet oxygen (¹O₂) has a critical role in the cell-killing mechanism of photodynamic therapy (PDT). Therefore, in this study, the distance-dependent reacted ¹O₂ is numerically calculated using finite-element method (FEM). Herein, we use a model [Ref. 1] that has been ... Mehr lesen

Electromagnetic Well Logs Simulated with the COMSOL® RF Module on a Cluster

D. Swaminathan[1], G. Minerbo[1], K. Pathak[1]
[1]Drilling and Production Group, Schlumberger, Houston, TX, USA

Introduction Computer simulations are widely used for the interpretation and inversion of electromagnetic measurements in well logging. Until recently, simulated logs have been computed with approximate 1D or 2D models. By using the COMSOL® RF Module installed on a cluster, we show that ... Mehr lesen
