Systematic Synthesis

The biplane counter-flapping wing is a special type of wing flapping which is inspired from the fish and insect in nature. The propulsive performance is one of the most important considerations for this kind of flapping wing. This paper is aimed at providing a systematic synthesis on the propulsive characteristics of two flapping wings at biplane configuration based on the numerical analysis approach. Firstly, parameters of this special flapping wing are presented. Secondly, the numerical method for simultaneously solving the incompressible flow and counter-flapping motion of the wing is illustrated, and the method is then validated. Thirdly, the effects of phase angle and mean wing spacing on the propulsive characteristics of the biplane counter-flapping wing are analyzed. Finally, the quantification effects of the phase angle and mean wing spacing on the propulsive characteristics of the biplane counter-flapping wing can be obtained. The analysis results in this study will provide useful guidelines to design an effectively propulsive system applying for the flapping micro air or underwater vehicle.

Steady Laminar

A numerical analysis of the steady, laminar, incompressible flow in a constant diameter tube with uniform mass suction at the wall is made to study the development of the flow for the entire range of wall Reynolds numbers. It is shown that for small suction rates the state of flow can reach the similarity condition at least at distinct positions at the tube axis. For higher suction rates similarity profiles are found to occur only if the flow exhibits an asymmetric behavior with respect to the point of complete mass extraction.
