Flow Optimization of a MVHR Combined with an Exhaust Air Heat Pump by Means of CFD Simulation

F. Ochs [1], M. Bianchi Janetti [1], M. Romani [2],
[1] University of Innsbruck, Unit Energy Efficient Buildings, Austria
[2] Galletti Group, Italy

In the framework of the Austrian FFG project SaLüΗ!, a compact mechanical ventilation system with integrated micro-heat pump was developed. The aim was a high level of prefabrication and a compact design allowing for installation also in small flats, e.g. into the façade. Due to the ... En savoir plus

The Origin of Mass-change Sensitivity within Multi-layered, Non-uniform, Piezoelectrically-actuated Millimeter-sized Cantilever (PEMC) Biosensors: Vibrational Analysis through Experiment and Finite Element Modeling (FEM)

B.N. Johnson[1], and R. Mutharasan[1]

[1]Department of Chemical and Biological Engineering, Drexel University, Philadelphia, Pennsylvania, USA

A 3D finite element model (FEM) of the PEMC sensor was developed to characterize the modes of vibration that have demonstrated high sensitivity to mass-change in experimentally fabricated sensors. The fundamental bending mode of vibration and the 1st bending harmonic are predicted at 10 ... En savoir plus

Mixing and Residence Time Distribution Studies in Microchannels with Floor Herringbone Structures

A. Cantu-Perez, S. Ping Kee, and A. Gavriilidis
University College London, Department of Chemical Engineering, Torrington Place, London, UK

The mixing characteristics and residence time distributions (RTDs) of a staggered herringbone microchannel have been investigated numerically by COMSOL Multiphysics and by particle tracking algorithms that incorporate diffusion via a random walk. All simulations were validated with ... En savoir plus

Modal Analysis of Elastic Ring Squeeze Film Damper for Small Gas Turbine Engines

S. Thennavarajan[1][2], P. Jeyaraj [1], L. P. Manikandan [2], S. S. Kulkarni [2], S. Jana [2],
[1]Department of Mechanical Engineering, NITK, Surathkal, Mangalore, Karnataka, India
[2]CSIR- National Aerospace Laboratories, Bengalore, Karnataka, India

The high speed gas turbine is a power plant developed for modern aircrafts. It is widely used and developed because it can meet the high power to weight ratio. The rotor system of modern small gas turbine works above the critical speeds. Hence, there is a stricter requirement for the ... En savoir plus

Multiphysics Simulation for Different Topology of Heat Sink Design

Aashish Kumar [1], Usha Dasari [1], Manoj Kumar Mondal [1],
[1] Indian Institute of Technology Kharagpur, Kharagpur, West Bengal, India

In recent times, the major concern in the area of microelectronics is efficient heat transfer which will improve the operating characteristics of the device as well as minimize its failure rate due to induced overheating. The removal of excess heat from the system can be done by ... En savoir plus

Micro cooling channel heat sinks designed by topology optimization

Hao Li [1], Xiaohong Ding [1], Dalei Jing [1], Min Xiong [1],
[1] University of Shanghai for science and technology

As a key component of MEMS, microprocessor with high computing performances is facing with severe thermal challenge due to the increasing power density, miniaturization as well as higher operating temperature requirements, and thermal management in corresponding fields has become one of ...

Reliability Evaluation for Static Chamber Method at Landfill Sites

H. Ishimori[1], K. Endo[1], and M. Yamada[1]
[1]National Institute for Environmental Studies, Tsukuba, Ibaraki, Japan

In this study, COMSOL Multiphysics was used for the reliability evaluation for static chamber method at landfill sites. Static chamber method, which measures landfill gas emission fluxes, is widely used at landfill sites for the monitoring of greenhouse gas emission such as methane and ... En savoir plus

Development of an On-Line Wall-Fouling Sensor for Pipeline Transportation of Heavy Oil-Water Mixtures

S. Rushd[1], and R.S. Sanders[1]
[1]Chemical & Materials Engineering Department, University of Alberta, Edmonton, AB, Canada

A beneficial method for transporting highly viscous hydrocarbons (e.g. heavy oil and bitumen) through a pipeline is known as Lubricated Pipe Flow (LPF). A major challenge for this technology is flow instability caused by the formation of a wall-coating of oil or the thinning and/or loss ... En savoir plus
