An ETC characterization system for thermal analysis of fluids is a mini closed-loop ETC system to study the thermal characteristics of various fluids. It uses an artificial sunlight so that it can be used inside a lab and is independent of the natural climate. A chiller is also connected to the system so that once fluids get heated, students will be able to cool it down immediately and study the thermal characteristics of heating as well as cooling. This system helps students in practical understanding of various technical parameters such as efficiency and heat transfer at different flexible input parameters like radiation, wind speed, etc. The system has inbuilt sensors that measure parameters like pressure, temperature, flow rate, etc., mounted on a control unit.
