Abstract

The unsteady flow behavior and time-dependent aerodynamic characteristics of the flapping motion of a bird’s wing were investigated using a computational method. During flapping, aerodynamic interactions between bird wing surfaces and surrounding flow may occur, generating local time-dependent flow changes in the flow field and aerodynamic load of birds. To study the effect of flapping speed on unsteady aerodynamic load, two kinds of computational simulations were carried out, namely a quasi-steady and an unsteady simulation. To mimic the movement of the down-stroke and the upstroke of a bird, the flapping path accorded to a sinus function, with the wing attitude changing in dihedral angle and time. The computations of time-dependent viscous flow were based on the solution of the Reynolds Averaged Navier-Stokes equations by applying the k-e turbulence model. In addition, the discretization for the computational domain around the model used multi-block structured grid to provide more accuracy in capturing viscous flow, especially in the vicinity of the wing and body surfaces, to obtain a proper wing-body geometry model. For this research, the seagull bird was chosen, which has high aspect ratio wings with pointed wing-tips and a high camber wing section. The results include mesh movement, velocity contours as well as aerodynamic coefficients of the flapping motion of the bird at various flapping frequencies.

Abstract

Teknologi monitoring akan diterapkan untuk melakukan pengambilan gambar atau dikenal dengan istilah face recognition dalam Sistem monitoring apsensi Pada SMK Budi Bhakti Mamasa. Tujuan penelitian ini adalah membangun sebuah sistem teknologi monitoring dalam Sistem absensi siswa berbasis pengambilan gambar untuk menjadi suatu system yang nantinya mempermudah dalam merekap data absensi siswa pada sekolah menengah atas di kabupaten Mamasa. Kesimpulan dari hasil penelitian ini adalah dengan terbangunnya Sistem monitoring apsensi Pada SMK Budi Bhakti Mamasa, yang akan mempermudah dalam melakukan absensi menggunakan pengambilan foto wajah, kemudian sistem melakukan identifikasi data berdasarkan gambar yang telah diambil pada database Monitoring Kehadiran Siswa tersebut, setelah hal tersebut maka data siswa yang telah diidentifikasi menggunakan pengambilan gambar wajah akan dikategorikan hadir dalam kelas tersebut sehingga mempermudah dalam melakukan pelaporan kehadiran siswa.
