The term hydrodinamika is used in several sub-fields in engineering marine, so in this activity it is necessary to emphasize the field of hydrodynamics discussed is related to the interaction between fluids and structures, especially interactions Sea waves with marine building structures. From this activity it is expected to be able developed a book that can be a good reference for engineering students marine (S1 or S2) and also for practitioners who use a lot of software Calculation of water wave style and analysis of marine building structures. Hydrodynamics contains words �Hidro� that comes from Greek which means water, While the word dynamics show something moving, in this case the water movement, Or in this case it is called fluid flow or water flow. Then in the field of hydrodynamics, The discussion will include water fluid flow. Hydrodynamics also known as branches or applications of mathematics, so the problem of fluid flow is generally Completed with a mathematical approach. The discussion is closed with topics regarding the movement of the structure (response) due to the load sea ​​waves, so it can be arranged in motion equations and, in turn, response from Sturktur can be predicted.
Application of writing
To facilitate understanding of mathematics, this book opened with a study reset the basics of mathematics associated and also review on the basics Fluid flow. Then given an explanation of linear wave theory along with kinematics aspects and dynamics, and (because the sea wave is a random phenomenon) equipped With marine wave statistics analysis and analysis in the frequency domain. Based on the linear wave theory can be developed for style analysis work on the structure of the sea building, due to sea wave load, where, Simple, analysis can be divided into three methods, depending on relative size Structure of wavelength and flow pattern around the structure. Which method Discussed is: diffraction theory (for large structures), Morison equation (for small sized structure), and froud krylov method (if there is no change Significantly on the flow pattern and does not appear to be used phenomenon).
