Mathematical modeling for complex fluids and flows

" The book develops a descriptive mathematical model articulated through continuum mechanics concepts for these non-Newtonian, viscoelastic fluids and turbulent flows. Each complex fluid and flow is examined in this continuum context as well as in combination with the turbulent flow of viscoelastic fluids. Some details are also explored via kinetic theory, especially viscoelastic fluids and their treatment with the Boltzmann equation. Both solution and modeling strategies for turbulent flows are laid out using continuum concepts, ... "

Tracer technology : modeling the flow of fluids

" The tracer method was first introduced to measure the actual flow of fluid in a vessel, and then to develop a suitable model to represent this flow. Such models are used to follow the flow of fluid in chemical reactors and other process units, in rivers and streams, and through soils and porous structures. Also, in medicine they are used to study the flow of chemicals, harmful or not, in the blood streams of animals ... "

An introduction to modeling and simulation of particulate flows

" The relatively recent increase in computational power available for mathematical modeling and simulation raises the possibility that modern numerical methods can play a significant role in the analysis of complex particulate flows. This introductory monograph focuses on basic models and physically based computational solution strategies for the direct and rapid simulation of flowing particulate media. Its emphasis is primarily on fluidized dry particulate flows in which there is no significant interstitial fluid, although fully coupled ... "

Flow-induced vibrations : classifications and lessons from practical experiences

" In many plants, vibration and noise problems occur due to fluid flow, which can greatly disrupt smooth plant operations. These flow-related phenomena are called flow-induced vibration. This book explains how and why such vibrations happen and provides hints and tips on how to avoid them in future plant design. The world-leading author team doesn?t assume prior knowledge of mathematical methods and provides the reader with information on the basics of modeling. The book includes several practical examples and ... "

Pengembangan model matematik untuk memprediksi viskositas kinematik campuran biner base oil dengan aditif fluida non-newtonian jenis olefin copolymers (OCPs) = Development of mathematical model for predicting the kinematic viscosity of liquid-binary mixtures of base oil with non-newtonian fluid additive type olefin copolymers (OCPs)

" Penyusunan formula minyak lumas selalu melibatkan penggunaan aditif yang bersifat non-Newtonian kuat, seperti viscosity modifiers, package additives dan component additives. Kehadiran fluida tersebut menyebabkan penyimpangan dalam memprediksi nilai viskositas kinematik campuran. Hasil studi pendahuluan menunjukkan bahwa metode Wright memiliki akurasi yang lebih baik dibandingkan dengan metode ASTM dan persamaan Refutas. Naumn demikian, ketiga metode tersebut masih menunjukkan penyimpangan nilai yang relatif tinggi, terlihat dari nilai percent average absolute deviation (% AAD). Tujuan penelitian ini adalah ... "

Gambaran jumlah kendaraan dengan pajanan PM2.5 di gerbang tol Cililitan tahun 2014 = Descriptive study about the number of vehicles with PM2.5 exposure in Cililitan toll gate in 2014

" Jumlah kendaraan di Jakarta bertambah setiap tahunnya. Hal ini mengakibatkan polusi udara dan kemacetan lalu lintas. Masyarakat di Jakarta biasanya akan menggunakan jalan tol untuk menghindari kemacetan sehingga jumlah kendaraan yang memenuhi jalan tol semakin bertambah setiap tahunnya. Penelitian ini bertujuan untuk mengidentifikasi konsentrasi pajanan PM2 di Gerbang Tol Cililitan Tahun 2014, dengan menggunakan desain studi deskriptif. Hasil penelitian menunjukkan konsentrasi PM2,5 di dalam gardu lebih tinggi dibandingkan konsentrasi PM2.5 di luar. Konsentrasi PM2.5 di ... "
