This study introduces a modular flap-type WEC in which a single flap is divided into two vertical segments. This modification aims to investigate its impact on power production. A dynamic model is developed for this dual-flap system, and the governing equations of motion of the system are derived. To account for the interaction between the flaps and the waves, hydrodynamic coefficients and excitation moments are computed using a Boundary Element Method (BEM), which takes the influence of wave-induced forces on each flap into consideration. The rotational motions of both flaps are then analyzed, with an assumption of regular waves. Furthermore, the power generated by each flap is calculated, based on their respective rotational responses. This analysis is aimed to evaluate the efficiency of the dual-flap configuration in harnessing wave energy.</span></span></span> Wave Energy Converter )WEC(,vertical double flap,power,water wave,Oscillating Wave Surge Converter (OWSC) 55 65 http://ijmt.ir/browse.php?a_code=A-10-4-3&slc_lang=en&sid=1 Hamid Bab hamid.bab@mech.sharif.edu 10031947532846004487 10031947532846004487 No Marine Engineering , School of Mechanical Engineering , Sharif University of Technology Mahdi Aziminia mm_aziminia@mech.sharif.edu 10031947532846004488 10031947532846004488 No Marine Engineering , School of Mechanical Engineering , Sharif University of Technology Abuzar Abazari abuzarabazari@cmu.ac.ir 10031947532846004489 10031947532846004489 No Associate Professor Marine Engineering , Chabahar Maritime University, Chabahar, Iran Mehdi Behzad m_behzad@sharif.edu 10031947532846004490 10031947532846004490 Yes Professor Mechanical Engineering , School of Mechanical Engineering , Sharif University of Technology
