Yogiraj K Shetty, Jayant M Modak

Abstract: In-order to meet the increasing demand of energy people are switching over to renewable source of energy. Bio-fuels to a larger extent has proven to be a very effective replacement to fossil fuel and hence stress is given on its production. Algal culture is gaining prominence. These algae are cultured in open raceway ponds and studies are being carried out to improve its efficiency. Hydrodynamics of water like vertical mixing, dead zone formation are few of the important parameters affecting the efficiency of raceway. Herein, study on the improvement of the hydrodynamics of a raceway from CFTRI has been done. Effectiveness of Delta wing (DW) in improving vertical mixing of pond was studied, furthermore parameters like DW angle of attack and number of DWs were optimized. In addition effectiveness of deflectors in solving the issue of dead zones at bends was studied.

Keywords: Algal pond, Delta Wings, Deflector, Vertical Mixing, Deadzones.
