Objectives :  

                   To enhance the heat transfer rate of the heat exchanger by 170 %

                   To enhance the effectiveness of the heat exchanger upto 0.85

                 To reduce the pressure drop of the flow thereby minimising the pump size directly&reducing the maintenance cost  &reducing the Space .

               To evaluate the performance characteristics of the Heat Exchanger under counter Flow arrangements .

METHODOLOGY :

       Passive Method : These methods generally use surface or geometrical modifications to the flow channel by incorporating inserts or additional devices.

                                      Conduction and convection heat transfer methods are used.

                                         

 SCOPE OF THE PROJECT

3-1The Following are the Scope of the Project

                            To find the Effectiveness of the Heat Exchanger.

                          To find the Heat Transfer rate.

                          To find the Convective Heat Transfer Co-Efficient.

                            To find the overall heat transfer coefficient.

3.2 NANOFLUID PREPERATION

                Nanoparticles of size less than 100nm suspended in fluids have led to a new innovative category of fluids called nanofluids. These fluids are of great interest because of their ability to enhance the heat transfer performance of the fluids and also the problems of fouling is less due to the nanometre size of the particles. In the present study multi walled carbon nanotubes of diameter 20nm, length 10 - 30µm and purity 95% procured from Cheap Tubes^® are used. The nanoparticles are dispersed in the base fluid  to have a volume fraction of 0.2%. A scanning electron microscope (SEM) image of the Nano Material fluid particle used is Al₂O₃ is shown in the figure below.
