In this research work, experimental analyses have been done for helical tube type heat exchanger. For these analyses, helical concentric tubes have been designed and fabricated. This heat exchanger contains two tubes of 6.0 meters length which are helical in shape. And these dimensions have been checked on CAD Tool Cero Parametric 2.0. Two sets of concentric tubes have been fabricated with copper and mild steel tube materials. After fabrication effectiveness, entropy generation, exergy destruction, entransy dissipation and entransy dissipation-based thermal resistance have been evaluated. All these thermodynamic analyses have been completed at various working conditions. Finally bar charts have been generated for various working conditions which show performance of the heat exchangers. All analysis have been performed for counter and parallel flow heat exchanger.
