Abstract EN
Entropy generation was studied for new type of heat exchanger (shell and double concentric tubes heat exchanger).
Parameters of hot oil flow rate, temperature of inlet hot oil and pressure drop were investigated with the concept of entropy generation.
The results showed that the value of entropy generation increased with increasing the flow rate of hot oil and when cold water flow rate was doubled from 20 to 40 l/min, these values were larger.
On the other hand, entropy generation increased with increasing the hot oil inlet temperature at a certain flow rate of hot oil.
Furthermore, at a certain hot oil inlet temperature, the entropy generation increased with the pressure drop at different hot oil inlet flow rates.
Finally, in order to keep up with modern technology, infrared thermography camera was used in order to measure the temperatures.
The entropy generation was determined with lower values when infrared thermography camera was used to measure the temperatures, compared with the values obtained by using thermocouples.
