Heat Transfer Simulation for Reliability Estimation of Additive Manufacturing Process using the COMSOL Multiphysics® Software

K. W. K. Leung [1], A. Keshtgar [1], N. Iyyer [1],
[1] Technical Data Analysis, Inc., Falls Church, VA, USA

Selective laser melting (SLM) is a popular additive manufacturing (AM) process that creates 3D metal parts by fusing fine metallic powder together. However, it remains difficult to certify AM part as its final quality can largely vary, depending on material and process variations. These ... Mehr lesen

On the Limitations of Breakthrough Curve Analysis in Fixed-Bed Adsorption

J. Knox [1],
[1] Marshall Space Flight Center - NASA, Huntsville, AL, USA

This work examined in detail the a priori prediction of the axial dispersion coefficient from available correlations versus obtaining it and also mass transfer information from experimental breakthrough data and the consequences that may arise when doing so based on using a 1-D axially ...

Optimization of Microstructures Used in CMOS-MEMS Devices Based on a Topological Design Process

J. Mares-Carreño [1], G. S. Abarca-Jiménez [2], M. A. Reyes-Barranca [2],
[1] Escuela Superior de Ingeniería Mecánica y Eléctrica, Instituto Politécnico Nacional, Ciudad de Mexico, D.F., Mexico
[2] Centro de Investigación y de Estudios Avanzados del Instituto Politécnico Nacional, Ciudad de México, D.F., Mexico

The paper exhibits the process followed to obtain the geometry of a support for a MEMS inertial sensor by means of a topology optimization process. The SIMP method is used for the optimization process in which the objective is to obtain a support structure with a minimum rigidity ... Mehr lesen

Thermo-mechanical Modeling of Pu-238 Production Target at HFIR

C.J. Hurt [1], J.D. Freels [2],
[1] University of Tennessee, Knoxville, TN, USA
[2] Oak Ridge National Laboratory, Oak Ridge, TN, USA

The production model in the COMSOL Multiphysics® software makes use of the most up-to-date PIE data, material property inputs, and modeling methodology. The fully coupled thermo-mechanical equations are solved over the entire domain, significantly increasing the degrees of freedom ... Mehr lesen

Glass Transition of ABS in 3D Printing

M. Rahman [1], N. R. Schott [2], L. K. Sadhu [3],
[1] North South University, Dhaka, Bangladesh
[2] Department of Plastics Engineering, University of Massachusetts - Lowell, Lowell, MA, USA
[3] IRays Teknology Ltd., Dhaka, Bangladesh

In a commercial 3D printer head, plastic ribbon passes through a hot nozzle of an extruder to dispense liquid plastic droplets to construct the model. In this paper a 2D axisymmetric model of a 3D head is considered to study the secondary transition change from below the glass ... Mehr lesen

Simulation and Testing of a Tunable Organ Pipe for Ocean Acoustic Tomography

A. K. Morozov [1],
[1] Teledyne Technologies Inc., Falmouth, MA, USA

Teledyne Marine developed a system for the long-range ocean acoustic tomography, which uses a tunable, high-efficiency sound resonator. The high-Q resonator tunes to match the frequency and phase of a reference frequency-modulated signal. The analysis of a high-Q resonant organ pipe with ... Mehr lesen

A Virtual Laboratory for the 4 Bed Molecular Sieve of the Carbon Dioxide Removal Assembly

R. Coker [1], J. Knox [1], B. O'Connor [1],
[1] Marshall Space Flight Center - NASA, Huntsville, AL, USA

Introduction: Ongoing work to improve water and carbon dioxide separation systems to be used on crewed space vehicles combines sub-scale systems testing and multi-physics simulations. Thus, as part of NASA’s Advanced Exploration Systems (AES) program and the Life Support Systems ... Mehr lesen

Finite Element Modeling of MEMS Chevron Thermal Actuators for Strain Engineering of Graphene

M. Vutukuru [1], J. Christopher [2], B. Goldberg [1,2], D. Bishop [1,2,3], A. Swan [1,2,3]
[1] Department of Electrical and Computer Engineering, Boston University, Boston, MA, USA
[2] Department of Physics, Boston University, Boston, MA, USA
[3] Division of Material Science Engineering, Boston University, Boston, MA, USA

Graphene, a single layer of carbon atoms, has demonstrated extremely high electric and thermal conductivities, tensile strength, and is therefore an exciting novel building block in the world of 2D flexible electronics. We propose the integration of graphene with MEMS devices to ... Mehr lesen
