Abstract: This paper presents the details of theoretical and numerical investigation of parallel flow heat exchanger. Theoretical or Empirical Formulae are used only for simpler geometry object but numerical technique can be used for complex geometry. Runge-Kutta fourth order numerical method is used here for high accuracy. Accuracy is also increased by increasing the number of elements. The numerical results had high degree of consistency and showed a perfect match with the theoretical readings. Using the parallel flow arrangement, the temperature difference between the hot and cold fluid dropped from 70 oC at the entry side to 40 oC at the exit of the heat exchanger
Keywords: Parallel flow heat exchanger, Numerical method, Theoretical method, Runge-Kutta fourth Order.
Scope of the Article: Heat Transfer
