Persamaan Euler merupakan salah satu penyederhanaan persamaan Navier-Stokes dengan asumsi inviscid, adiabatik serta menghilangkan efek dari body force. Pada aliran kompresibel, persamaan Euler merupakan sistem pesamaan hiperbolik non-linear untuk hukum konservasi. Pada aliran kompresibel, munculnya fenomena diskontinuitas berupa gelombang kejut sering menimbulkan masalah dalam simulasi, terutama dalam hal akurasi. Pada skema Godunov, akurasi interpolasi untuk memperoleh fluks pada batas antar sel dapat ditingkatkan dengan penggunaan limiter. Salah satu limiter orde tinggi yang dapat digunakan dalam ...

Turunan formula Navier-Stokes dipakai untuk menghitung kerugian tekanan aliran dalam pipa. Panjang pipa, diameter pipa, kecepatan fluida, kekasaran permukaan dan koefisien gesek yang mempengaruhi nilai kerugian tekanan. Formula tersebut tidak berlaku pada belokan/cabang pipa, setelah katup, adanya perubahan diameter (unsteady flow), adanya getaran, dll. Drag reduction dari solusi surfactant atau biopolymer telah menarik perhatian dari sisi konversi energy, dikarenakan penurunan secara mekanis tidak terjadi tetapi menghasilkan drag reduction yang besar di kondisi konsentrasi tertentu ...

Researchers and graduate students in applied mathematics and engineering will find Initial-Boundary Value Problems and the Navier-Stokes Equations invaluable. The subjects addressed in the book, such as the well-posedness of initial-boundary value problems, are of frequent interest when PDEs are used in modeling or when they are solved numerically. The book explains the principles of these subjects. The reader will learn what well-posedness or ill-posedness means and how it can be demonstrated for concrete problems. ...

This second edition, like the first, attempts to arrive as simply as possible at some central problems in the Navier-Stokes equations in the following areas: existence, uniqueness, and regularity of solutions in space dimensions two and three; large time behavior of solutions and attractors; and numerical analysis of the Navier-Stokes equations. Since publication of the first edition of these lectures in 1983, there has been extensive research in the area of inertial manifolds for Navier-Stokes ...
