Homogeneous Heating of Milk

A. Stahel, and A. Reichmuth
Berner Fachhochschule
Biel, Switzerland

When milk is taken out of a refrigerator it has to be heated up to 37°C. The standard solution is to put the bottle in a bath of warm water and wait. The goal is quickly to achive a uniform temperature of 37°C, without ever exceeding 40°C. Using COMSOL Multiphysics and a measurement ... Mehr lesen

MEMS-based Handy Fuel Adulteration Detection Device

Anumeha Dwivedi[1], Dr. R. Dey[2]
[1]BITS Pilani K.K. Birla Goa Campus, Goa, India
[2]Associate Professor, BITS Pilani K.K. Birla Goa Campus, Goa, India

Adulteration of automobile fuels, especially petrol and diesel is a rampant malpractice in India. With the rising prices of fuel and the subsidy on kerosene, getting away with even 10-15% adulteration is immensely profitable.To check adulteration effectively, it is necessary to monitor ...
