The Solar Parabolic Trough Collector Based System consists of parabolic reflectors, absorber tube, sun tracker, piping, storage tanks and a heat exchanger. A control panel would control different devices and also measure the different parameters of the system.  The system can be used to perform experiments in heat transfer, parabolic trough characteristics and heat loss at different parts of the system. The system is highly flexible – it can be used with different working fluids, different absorbing materials, different piping insulation thickness and different types of storage tanks. This gives a lot of scope for research in heat transfer and related fields. Wind speed variation and flow velocity are other parameters which can be changed to show their impact on heat transfer and heat loss.
