The present study focuses on the design and analysis of a single-engine, propeller-driven general aviation airplane. Initial weight estimation based on the initial sketch and the design mission profile is conducted. The estimated weight and other design parameters are used to define the external geometry of the fuselage, wing and tail. Conic lofting is utilized to render a layout of the design ...

Our goal is to reproduce the key features of carangiform swimming by running 2D simulations which fully exploit the Fluid-Structure Interaction interface of COMSOL Multiphysics software. Fish swimming is an important area of research, with relevant developments on biomechanics, robotics and mathematical modeling. Usually, in fish swimming simulations, the motion of the fish is assigned, and much ...

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 satellite (CubeSat) containing fiber reinforced SLS parts has been successfully launched (Ref 1). Lower ...

In this paper we made an attempt to maximize the power output in the different piezoelectric materials in a unimorph cantilever beam configuration. In this research, a macro scale unimorph piezoelectric power generator prototypes consists of an active piezoelectric layer, stainless steel substrate and titanium proof mass was designed for frequencies 60 Hz - 200 Hz. An analytical model of a micro ...

In this paper, a model for numerically obtaining lamb wave modes and dispersion curves in plates is presented. It is shown that COMSOL Multiphysics can be employed to simulate the behavior of guided waves in dispersive plates, which is useful for NDE applications. A two dimensional steel plate (4x0.1 meters) is excited with a space-time impact point source. To model the point source, we use ...

COMSOL Multiphysics was used to design a binocular load cell. A three-dimensional linear solid model of the load cell spring element was studied to quantify the high-strain regions under loading conditions. The load cell was fabricated from 6061 aluminum, and general purpose Constantin alloy strain gages were installed at the four high-strain regions of the spring element. The four gages were ...

The goal of a tokamak is to use high magnetic fields to contain plasma and produce nuclear fusion that can be used for power generation. MIT’s Plasma Science Fusion Center (PSFC) and collaborators are proposing a machine, the Advanced Divertor eXperiment (ADX) to test new technology for these systems at reactor level heat fluxes and magnetic fields. COMSOL Multiphysics® software is used to ...

Peristaltic pumping is an inherently nonlinear multiphysics problem where the deformation of the tube and the pumped fluid are strongly coupled. We used COMSOL Multiphysics to investigate the performance of a 180 degree rotary peristaltic pump with two metallic rollers, and an elastomeric tube pumping a viscous Newtonian fluid. The model captures the peristaltic flow, the flow fluctuations ...

Introduction: Glass relaxation occurs in a range of temperature during transition from equilibrium to super-cooled liquid. Viscoelastic material model can be applied to simulate glass behavior during the glass transition regime and to predict the glass deformation and stress evolution. Viscoelasticity is the property of materials that exhibit both viscous and elastic characteristics when ...

High Pressure Processing (HPP) is a leading non-thermal food processing technology that is often cited as a major technological innovation in food preservation. Although it is very early to place this emerging technology among the list of breakthroughs in food processing, HPP has started to become a viable commercial alternative for pasteurisation of value added fruits, vegetables, meat, and ...
