The Influence of Mounting Angle on Gurney Flap on The Aerodynamics Performance of NACA 0015 Using CFD Method
Get PDFImproving the airfoil aerodynamics is quite an essential aspect of the aviation industry. One method for improving airfoil aerodynamics involves applying passive flow control techniques. The effect of using the gurney flap as passive flow control was explored through the CFD approach with the RANS control equation and incorporating k-epsilon as a turbulence model. The airfoil model utilized in this study was the NACA 0015 airfoil operating at a Reynolds number of 1×106. This study explored three different mounting angles of the gurney flap, namely 45°, 60°, and 90°. The outcomes show that adding the gurney flap has positive results in increasing the lift and drag of the NACA 0015. An airfoil with a mounting angle flap of 45° has an average percentage increase in Cl of 23%, followed by a mounting angle flap of 60°, which is 28%, and a percentage Cl of 45% for a mounting angle flap of 90°. Meanwhile, Gurney flaps with a mounting angle of 45° can increase Cd by an average percentage of 3%, while mounting angle flap at 60° increases the Cd percentage by 4% and 5% for a mounting angle of 90°. Moreover, fluid flow visualization with pressure and velocity contours was given at AoA 10º to determine its effect on increasing lift and drag on the NACA 0015 airfoil

Perbandingan Harga Opsi Reset dengan Metode Monte Carlo Standar dan Control Variate
Get PDFOpsi bermanfaat untuk melindungi investor dari risiko kenaikan atau penurunan harga saham. Opsi yang digunakan dalam penelitian ini adalah opsi reset dengan tipe call dan put yang bersifat path-dependent. Dalam kebanyakan kasus, opsi yang bersifat path-dependent tidak memiliki solusi analitik sehingga perlu dilakukan pendekatan numerik untuk menghitung harga wajar opsi jenis ini. Dalam penelitian ini, metode numerik yang digunakan adalah metode Monte Carlo standar dan Monte Carlo control variate. Ditunjukkan pula bahwa harga opsi reset yang dihitung menggunakan kedua metode tersebut konvergen menuju solusi eksak. Hal ini menandakan bahwa kedua metode dapat digunakan untuk menentukan harga opsi reset. Hasil penghitungan kedua metode tersebut kemudian dibandingkan berdasarkan kecepatan kekonvergenannya yang dihitung menggunakan galat relatif yang dihasilkan dari masing-masing metode. Metode Monte Carlo control variate menghasilkan galat relatif yang lebih kecil dibandingkan dengan Monte Carlo standar pada kedua tipe opsi. Hal ini menunjukkan bahwa metode Monte Carlo control variate merupakan metode yang lebih akurat dibandingkan metode Monte Carlo standar. Pengaruh nilai parameter model juga dibandingkan untuk menentukan harga opsi reset. Nilai volatilitas yang semakin besar membuat harga opsi reset cenderung semakin mahal pada kedua tipe opsi reset. Waktu reset yang semakin dekat dengan tanggal terbit opsi ataupun waktu jatuh tempo opsi menyebabkan harga opsi reset cenderung semakin murah. Sedangkan tingkat bunga bebas risiko menyebabkan perubahan perilaku harga yang berbeda pada opsi put dan call. Dengan meningkatnya tingkat bunga bebas risiko, harga opsi call akan semakin meningkat, sedangkan harga opsi put semakin menurun
