[2]National institute of Technology, Calicut, Kerala, India.

Liquid transport in lab-on-a-chip (LOC) devices occurs through a microchannel that uses an electroosmotic flow actuation mechanism. This method has a plug-like velocity profile, which is ideal in species transport and in wall-bounded reactions. Under substantial joule heating, it is not ... Mehr lesen

Structural Durability Analysis of Powertrain Mounting Bracket

[1]United Institute of Technology,Coimbatore,Tamil Nadu, India

Monitoring the Central aorta is a more effective way to diagnose cardiovascular diseases than conventional techniques. Approximately, six million people in the world are currently living with aortic aneurysm and every year 750,000 new cases are diagnosed. This paper presents the design ... Mehr lesen

CFD Analysis of Ejectors

Vikas N Bhargav[1], Vivek Ganeshan[1], Muralidhara Holla[1], Ramesh Kolluru[1]
[1]Mechanical Engineering Department, BMS College of Engineering, Bangalore, India

Ejectors are the devices used to carry out mixing and recompression of two fluid streams, one with higher energy and the other with lower Energy. The high energy fluid is passed through the converging nozzle of ejector to very high velocities which in turn creates suction and draws the ... Mehr lesen

The EM optimization of a coarsely discretized model of a microstrip band-pass filter implemented in COMSOL Multiphysics® was realized using two different model configurations. We presented a systematic methodology to find an appropriate 3D EM model configuration on a direct EM ... Mehr lesen

Models with Helical Symmetry Studied in a 2D Plane

M. Weterings[1], M. Beyrer[1]
[1]Institute of Life Sciences HesSo Valais, Sion, Valais, Switzerland

Partial differential equations (PDEs) in multiple dimensions may often be solved in a lower dimension if the problem domain contains a symmetry (cylindrical, spherical, translational, etcetera). For problems involving PDEs with helical symmetry we propose a method, with both low ... Mehr lesen
