CFD Analysis of Fish Movement in Open Channel under Laminar Flow Condition
Understanding the movement techniques of a fish in water has numerous applications far outside of biology. Biological propulsion has evolved over millions of years into a finely refined, efficient system of locomotion which cannot be matched by any technique developed by man. Thus leaving man no other options but studying the techniques engineered by nature itself. The objective of the paper is to study the motion of a fish in an open channel flow by CFD analysis of a fish under laminar flow conditions. The different step of fish positions was created by surface modelling in a CAD platform Solidworks 15.0 to study its movements. The purpose of this simulation was to learn the performance and usability of a method of surface model analysis based CFD. A CFD tool ANSYS Fluent version 16.2 was used to do the finite volume analysis of the fish models. The analysis is done on the fish profile over a square domain by creating mesh ANSYS Fluent itself. The analysis was done to study the pressure and velocity gradients generated at different points of the fish contour which aid the fish movement in an upstream condition. The lift and drag co-efficient are obtained after the analysis. The result shows how the fish produce thrust by moving its body parts in rhythmic manner.
