Abstract :

Abstract-- The proposal of this project is to fabricate a cooling curve plotting unit for analysis of different coolants. The rate of cooling can be determined from a cooling curve that can be plotted with the help of a cooling curve plotting unit. The cooling curve can be plotted using a temperature sensor- microcontroller arrangement. In this analysis we are using engine oil and coconut oil as coolants. Mild steel and aluminium are the specimens. We analyse the different combinations of the coolant and specimen using the arrangement. The specimen is first heated in a heating chamber which is a convective oven and maintained at the required temperature. It is then introduced into a cooling chamber where the different coolants are used. The temperature change of the material is monitored at regular intervals from the beginning to the end and is recorded by a microcontroller known as Arduino. The varying temperature is sensed by a micro controller using LM 35.The microcontroller records the temperature change at regular intervals and stores the data in a SD card via an adaptor. The data stored in the SD card can be read using Microsoft excel and the cooling curve is plotted. Thus the best suited combination for different applications can be selected.
