Holaaa
Perkenalkan nama saya Josiah Enrico S dari jurusan teknik mesin FTUI. Sebagai salah seorang mahasiswa, saya senang belajar dan berbagi banyak hal baru kepada dunia. Melalui wiki ini, saya akan berbagi kepada kalian tentang apa yang saya pelajari. :)
Gate Valve - Metode Numerik/18 November 2020
Berikut ini adalah contoh penerapan aplikasi OpenModelica untuk menyelesaikan metode numerik roots of equation (akar persamaan):
1. Metode Terbuka
*Newton Raphson
*Newton Raphson model Secant_Algorithm parameter Real a=0; //guess parameter Real b=1; //guess parameter Integer N=10; //max iteration parameter Real er=0.0000001; //error maximum Real A[N]; Real B[N]; Real y[N]; Real ER[N]; Real sol; //solution
algorithm
A[1]:=a; B[1]:=b; y[1]:=B[1]-(exp(-B[1])-B[1])*(A[1]-B[1])/((exp(-A[1])-A[1])-(exp(-B[1])-B[1])); ER[1]:=abs(1-B[1]/y[1]);
for i in 2:N loop A[i]:=B[i-1]; B[i]:=y[i-1]; y[i]:=B[i]-(exp(-B[i])-B[i])*(A[i]-B[i])/((exp(-A[i])-A[i])-(exp(-B[i])-B[i])); ER[i]:=abs(1-y[i-1]/y[i]);
if ER[i]<er then sol:=y[i]; break; end if; end for;
end Secant_Algorithm;
Gate Valve - Aplikasi CFD/12 November 2020
Gate Valve
membuka atau menutup aliran
Mengatur kecepataan fluida (Regulasi)
Mangatasi Backflow atau aliran balik
