A new special channel named as double wavy channel is presented. Based on the method of orthogonal experiments
9 double wavy channels with different structural parameters were designed. In certain Reynolds number range (25≤Re≤200)
the characteristics of fully developed laminar flow and heat transfer for the 9 double wavy channels were considered using computational fluid dynamics technology. The fluid flow experimental set for the channel was designed and manufactured
and flow velocities of special points in the channel were measured using laser Doppler velocimeter. It is concluded that the wave amplitude of the channel has significant effect on the characteristics. The numerical simulation results are in accordance with the experimental results and the maximum relative error of the main velocity is 28.7%. The validity and accuracy of the numerical simulation are verified.
