triple flow, counter flow, vibration, nusselt number, and heat transfer coefficient ;
In this, the performance and advancement of triple flow heat exchanger is determine and presented graphically in terms of temperature, effectiveness of two of the fluids. The effectiveness is determined as a function of heat exchanger size for sets of fixed operating temperature condition. In this experiment were performed to investigate the effect of vibration on the heat transfer characteristic of flow in circular heated pipe. Water is used as working fluid with inlet Reynolds number between the range of 400 to 1100 and vibration acceleration is varying from 1g to 5g. The results demonstrated that mechanical force vibration significantly influences the heat transfer in a cold pipe flow. The Nusselt number increases with the vibration acceleration. The Nusselt number increases rapidly when the vibration frequency increases but change in Nusselt number increasing first then start decreasing. Effectiveness and efficiency parameter are determined for a wide range of operating parameter for counter flow.
