Uppsala University wants to make a wave tank which can be used for experiment and education purpose. The project's aim is to get design parameters required to make a wave tank, design the wave tank, to do analysis on wave parameters taken from results and analysis of material which can be used to construct it. This project is an extension of the project called Numerical Wave Tank Design in which a literature study on existing wave research facilities was done [1]. The data from this project is used to get the dimensions of the wave tank. A study on hydrodynamics and wave theory is done to understand flow motion and wave generation. Ansys Fluent is used for Computational Fluid Dynamics (CFD). The software is used to test the wave tank with different wave absorber and observe if a good quality wave with a minimal reflection can be generated in the wave tank of chosen dimensions. Four models were created for testing wave absorber of different shapes. The setup for all the models was kept the same for comparison purposes. Waves generated from CFD were later compared with the theoretical waves obtained from wave theory. The next part was to model the wave tank in Computer-Aided Design (CAD) software, SolidWorks. The stress and strain analysis was done on the walls and support beam of the wave tank to know if the structure can sustain the water when fully filled. After creating static simulation different scenarios were performed on the beam and stand of the wave tank. The design study on these parts was compared to see which case provides a more optimal solution. It was found out that wave absorber having an elevation of 18.4 degrees, i.e., 1:3 slope provides the highest wave height for the given parameter and dimensions of the wave tank. In wave analysis, it was seen that wave height is proportional to the stroke length, water depth is proportional to wave height and time period is inversely proportional to the wave height. Cast stainless steel is used in a wave tank as it is cheap, reliable and robust. It was found out that the support beam 0.015 m thick is enough, although it can be increased to 0.02 m. In the design study of the wave tank stand, it was found out that a leg distance of 0.78 m and a leg width of 0.06 m is sufficient to withstand the weight of the wave tank.
