Résumé

An indigenous programme on design and development of a small high speed cryogenic turboexpander has been taken up at NIT, Rourkela. This paper aims at the development of a small high speed cryogenic turboexpander in Indian condition by using aerodynamic thrust bearings. Attention has been paid to the study of the performance of turboexpander and the effect of stability on the vibration of bearings. Series of tests were conducted to confirm the findings. The maximum rotational speed obtained was 200,000 rpm and a temperature drop of 30°C. The outcome may help the designers, researchers and manufacturer of these components.
