Numerical analysis study of Sarawak barrage river bed erosion and scouring by using Smooth Particle Hydrodynamic (SPH)

Numerical analysis study of Sarawak barrage river bed erosion and scouring by using Smooth Particle Hydrodynamic (SPH) / Mohd Khairun Nizar Mohd Tajudin
Smooth Particle Hydrodynamic (SPH) adalah model simulasi tiga dimensi. Dalam kajian yang dijalankan ini, tiga situasi dan satu situasi pengesahan telah disimulasikan menggunakan DualSPHysics. Kawasan kajian yang dijalankan adalah Sarawak baraj. Situasi yang dipilih untuk menjalankan kajian adalah dengan pembezaan paras air pada hilir sungai. Kajian ini sebenarnya bertujuan untuk mensimulasikan hakisan dasar sungai dan rupa bentuk kerukan yang terjadi dengan menggunakan kes dua fasa dimana menggunakan pasir sebagai sedimen dan air. Halaju dan rupa bentuk kerukan telah direkodkan dan dipaparkan dalam bab hasil keputusan. Keputusan yang diperolehi dari kajian pengesahan boleh diterima pakai dimana profil kerukan dan halaju mempunyai sedikit perbezaan antara ujikaji makmal dan simulasi. Oleh itu, kesimpulan yang boleh dibuat adalah simulasi dengan menggunakan SPH boleh digunakan sebagai alternatif untuk mensimulasikan situasi sebenar. _______________________________________________________________________________________________________ Smooth Particle Hydrodynamic is the three-dimensional (3D) model. In this research work, three cases and one validation have been simulate using DualSPHysics. Study area of this research work was at Sarawak Barrage. The cases have different water level at the downstream. This study actually to simulate riverbed erosion and scouring properties by using multi-phases cases which use sand as sediment and water. The velocity and the scouring profile have been recorded as the result and shown in the result chapter. The result of the validation is acceptable where the scouring profile and the velocity were slightly different between laboratory experiment and simulation. Hence, it can be conclude that the simulation by using SPH can be used as the alternative to simulate the real cases.
