"This book offers a mathematical update of the state of the art of the research in the field of mathematical and numerical models of the circulatory system. It is structured into different chapters, written by outstanding experts in the field. Many fundamental issues are considered, such as : the mathematical representation of vascular geometries extracted from medical images, modelling blood rheology and the complex multilayer structure of the vascular tissue, and its possible pathologies, the mechanical and chemical interaction between blood and vascular walls, and the different scales coupling local and systemic dynamics. All of these topics introduce challenging mathematical and numerical problems, demanding for advanced analysis and efficient simulation techniques, and pay constant attention to applications of relevant clinical interest.

"Metode Smoothed Particle Hydrodynamics sebagai altenatif model numberik untuk menyelesaikan permasalahan fisika fluida telah berkembang pesat. Satu dari simulasi yang menggunakan metode ini adalah simulasi model aliran fluida tiga dimensi pada penyempitan pipa vertikal. Untuk mendapatkan output realistis pada aliran fluida tiga dimensi, dalam penelitian, penulis akan menguji simulasi aliran fluida pada penyempitan pipa vertikal berpenampang lingkaran dengan melihat kestabilan pengujian menggunakan hukum kekekalan massa dan energi. Dalam penguantifikasian hukum kekekalan energi, digunakan juga minor loss sebagai salah satu paratameter kestabilan pada pengujian ini.
Untuk menguji simulasi ini, penulis menggunakan compiler program, FORTRAN, untuk keefektifan pengujian. Pengujian dilakukan pada tiap skenario pada 100 iterasi dengan time step 0,01 s menggunakan jumlah partikel inisiasi untuk dimasukkan ke dalam program dengan variasi jumlah kernel particles. Hasil perhitungan kekekalan massa dan energi yang diperoleh berupa nilai residu mendekati angka 0 pada saat t = 0,0 s hingga t = 0,56 s namun mengalami peningkatan dan berfluktuasi pada t berikutnya dengan prosentase residu terhadap total massa ataupun energi sangat rendah. Hasil perhitungan minor loss menunjukkan nilai minor loss coefficient cenderung semakin turun dengan semakin banyak jumlah partikel inisiasi yang digunakan pada 1,833 hingga 2,836.

Smoothed Particle Hydrodynamics method as the numeric modelling alternative to solve the fluid physics problem has developed rapidly. One of the simulations that use this method is model simulation for three dimensional fluid flow on vertical pipe contraction. To get the realistic output for three dimensional fluid flow, in this research, the author will test the simulation of fluid flow on circular vertical pipe with observing the stability of the testing using the the conservation of mass and conservation of energy. In the quantification of the conversation of energy, it also uses the minor loss as one of the stability parameter fot this testing.
To test this simulation, author uses the compiler program, FORTRAN, for the effectiveness of the testing. The tests performed on each scenario on 100 iterations with timestep of 0,01 s using the initial number of particles to be input the program with a variety number of kernel particles. The result of mass and energy conservation calculation obtained as shown by the residue is near the number of 0 on t 0,0 s to t 0,56 s however it happens the increasing and fluctuate on the next t with the very lower percentage of residue to the total of mass or even energy. The result of minor loss shows that the minor loss coefficient is more decreasing as the bigger the number of initial particles used at the number of 1,833 to 2,836.

"This Handbook provides researchers, faculty, design engineers in industrial R&D, and practicing engineers in the field concise treatments of advanced and more-recently established topics in thermal science and engineering, with an important emphasis on micro- and nanosystems, not covered in earlier references on applied thermal science, heat transfer or relevant aspects of mechanical/chemical engineering. Major sections address new developments in heat transfer, transport phenomena, single- and multiphase flows with energy transfer, thermal-bioengineering, thermal radiation, combined mode heat transfer, coupled heat and mass transfer, and energy systems. Energy transport at the macro-scale and micro/nano-scales is also included. The internationally recognized team of authors adopt a consistent and systematic approach and writing style, including ample cross reference among topics, offering readers a user-friendly knowledgebase greater than the sum of its parts, perfect for frequent consultation. The Handbook of Thermal Science and Engineering is ideal for academic and professional readers in the traditional and emerging areas of mechanical engineering, chemical engineering, aerospace engineering, bioengineering, electronics fabrication, energy, and manufacturing concerned with the influence thermal phenomena."
