Item Holistic approach to project CWC with altair(Altair Technology Conference, 2015-07) Bhavaraju, Pradeep J. S.A Circulating Water Channel (CWC) generates a controlled flow environment and is used for various hydrodynamic research activities including flow around ships, study of fishnets, etc. The current paper utilizes various modules of ALTAIR HYPERWORKS to provide a holistic solution in completing the project i.e, modelling using SOLIDTHINKING, flow analysis across the working section of the CWC using ACUSOLVE, and developing a mechanism to generate ship motions with MOTIONSOLVE. One of the many experiments that can be conducted with the CWC is an internal tank sloshing test. A free surface flow analysis is performed for a 2D tank using RADIOSS solver validating the same with existing experimental results.Item Qualitative and quantitative analysis in comparing prospective CWCs(International Journal of Innovation Research & Development, 2015-07) Bhavaraju, Pradeep J. S.Qualitative analysis either involves traditional deductive logic beginning with assumptions and carefully deducing an outcome from them, or, a holistic approach in which all the factors and criteria involved are laid out in advance in a hierarchy or in a network system that allows for dependencies. Quantitative analysis involves estimating Life Cycle Costs to arrive at an economic equitable assessment of competing design alternatives considering total expenditures over its-entire economic life. The paper applies ualitative and Quantitative concepts to choose prospective designs of two configurations of the CWC i.e, the Vertical and the Horizontal orientations. Solutions are proposed to evaluate overall performance of the CWC.Item Comparative study for resistance of a bulk carrier using CFD(Altair Technology Conference, 2013-07) Bhavaraju, Pradeep J. S.; Revathi, Ch.; Ramesh, U. S.The hydrodynamic performance of a vessel depends on the shape of the hull. Therefore it is important that the hull form be carefully designed to minimize pressure distribution and resistance. A CFD analysis for the full scale bulk carrier is made to estimate the resistance at different velocitie . A 3D steady state, incompressible viscous flow analysis for 8, 12 and 14 knots at 7.8 m draft level is executed for zero offset flow angle using the CFD package ACUSOLVE and the results are compared with experimentally obtained model test results. An attempt is made to simulate free surface interaction between the bulk carrier and water using the Smooth Particle Hydrodynamics method available in RADIOSS solver.
