5.4 Experimental Setup
The experimental setup consists of a parabolic dish, a receiver with thermocouples, a
Coriolis flow meter, a 0.5 hp pump, 200 L tank and data acquisition system (make NI).
Coriolis flow meter is used to measure the mass flow rate in the system. The K-type
thermocouples are attached on to the receiver and the temperature is recorded using
NI DAQ system. The water is pumped using a 0.5 hp pump from the reservoir filled
with 200 L of water and mass flow rate is controlled using a seat valve. The mass flow
rate in the experiment is 0.03 kg/s and the parabolic dish is tracked manually with
respect to sun. Solar radiation is reflected by the parabolic dish on to the receiver
and this radiation is absorbed by the serpentine copper tubes. The water is kept
circulating inside the copper tubes with the help of pump. The heat transfer takes
place between the copper tube and the water flowing through it and the temperature
rises. It is to be noted here that the system is single pass and hence the temperature
rise is limited by that. The serpentine pipe is coated with black paint for higher
