Experimental Study of Heat Transfer between Two Cryogens

Cryogens and their uses are become essential from day to day life. Cryogens used for liquefaction of gases to storage of gases. Cryogen like nitrogen has wide uses in practical applications, which is easily available. According to temperature required different cryogens with respect to their properties used in various applications. This dissertation is focused on heat transfer between two cryogens. It is known that cryogens have their own evaporation rate, boiling point, freezing point and also have rate of heat transfer with respect to other objects that may be solid surfaces, stored food, insulating surfaces or cryogens in solid state or liquid state or gaseous state etc. In this dissertation heat exchanger will be designed to study that with variation in different parameters like tube length, material of tube how it affect the rate of heat transfer will be studied by running experiment, on basis of that, the data will be analysed.
