Fluid-structure interaction (FSI) refers to a class of problems in which the motions of fluid and solid are coupled. FSI is of great significance in many applications such as aero-elasticity, biomechanics, and design of various engineering systems. Typically, the multiphysics involved in ... 詳細を見る

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 ... 詳細を見る

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 ... 詳細を見る

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 ... 詳細を見る

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 ... 詳細を見る

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 ... 詳細を見る

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 ... 詳細を見る

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 ... 詳細を見る

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 ... 詳細を見る

In-service detection of fatigue cracking in metallic aerospace structures relies on capable and efficient eddy current inspection procedures. For best results, inspections with surface scanning eddy current techniques are following rigorous procedures that indicate the instrument ... 詳細を見る
