"Analysis of turbulent flows is written by one of the most prolific authors in the field of CFD. Professor of Aerodynamics at SUPAERO and Director of DMAE at ONERA, Professor Tuncer Cebeci calls on both his academic and industrial experience when presenting this work. Each chapter has been specifically constructed to provide a comprehensive overview of turbulent flow and its measurement. Analysis of Turbulent Flows serves as an advanced textbook for PhD candidates working in the field of CFD and is essential reading for researchers, practitioners in industry and MSc and MEng students.The field of CFD is strongly represented by the following corporate organizations : Boeing, Airbus, Thales, United Technologies and General Electric. Government bodies and academic institutions also have a strong interest in this exciting field."

"Turbulensi lingkungan pada industri keuangan menstimuli perusahaan untuk mendapatkan komponen pemasaran baru yang bersifat substitusi agar dapat mengatasinya. Perubahan pasar, intensitas kompetisi yang makin kompleks dan layanan teknologi keuangan yang semakin canggih menyebabkan selera nasabah rentan berubah serta sumber daya wajib diperbaharui. Penelitian ini bertujuan untuk menguji pengaruh dari turbulensi lingkungan terhadap kepemimpinan kewirausahaan dan kapabilitas dinamis. Tujuan berikutnya menguji kapabilitas dinamis dan kepemimpinan kewirausahaan terhadap strategi pemasaran perusahaan. Penelitian ini dilakukan secara kuantitatif. Fokus penelitian dengan studi kasus di PT Pegadaian (Persero). Pengukuran dilakukan dengan menyebarkan kuesioner kepada para pelaksana operasional PT Pegadaian (Persero) di seluruh Indonesia. Penelitian ini melakukan pengujian hipotesis menggunakan SPSS 23. Temuan yang diperoleh bahwa turbulensi lingkungan memengaruhi secara signifikan terhadap kapabilitas dinamis maupun kepemimpinan kewirausahaan. Demikian juga kapabilitas dinamis memengaruhi secara positif signifikan terhadap pemasaran kewirausahaan. Selanjutnya, kepemimpinan kewirausahaan tidak memengaruhi secara signifikan terhadap pemasaran kewirausahaan. Semua hipotesis ini memiliki implikasi secara teoritis dan manajerial. Implikasi teoritis yakni memberikan kontribusi dengan memperkaya konsep dari kepemimpinan dan kapabilitas dinamis dalam memengaruhi strategi pemasaran perusahaan untuk menghadapi turbulensi lingkungan. Sementara itu, implikasi untuk PT Pegadaian (Persero) agar selalu memantau setiap pengembangan pasar, mengkonfigurasi ulang sumber daya, menciptakan diversifikasi produk/layanan dan memperkuat hubungan dengan nasabah untuk jangka waktu yang lama.

Environmental turbulence in the financial industry stimulates companies to obtain new marketing components that are substitution in order to overcome them. Market changes, increasingly complex competition intensity and increasingly sophisticated financial technology services cause the tastes of vulnerable customers to change and resources must be renewed. This study aims to examine the effect of environmental turbulence on entrepreneurial leadership and dynamic capabilities. The next objective examines the dynamic capabilities and entrepreneurial leadership on marketing strategy of company This research was conducted quantitatively. For of research with case studies at PT Pegadaian (Persero). Measurements were taken by distributing questionnaires to PT Pegadaian (Persero) operational implementers throughout Indonesia. This study conducted hypothesis testing using SPSS 23.

The findings obtained that environmental turbulence significantly influences the dynamic capabilities and entrepreneurial leadership. Likewise dynamic capabilities have affect to entrepreneurial marketing. Furthermore, entrepreneurial leadership dont have influences to entrepreneurial marketing. All of these hypotheses have theoretical and managerial implications. Theoretical implications namely contributing to enrich the concepts of entrepreneurial leadership and marketing and dynamic capabilities in influencing marketing strategy of company to deal with environmental turbulence. Meanwhile, the implications for PT Pegadaian (Persero) to always monitor every market development, reconfigure resources, create product/service diversification and strengthen customer relationships for a long time."

"This paper presents a numerical analysis of gas flow in the annular combustion chamber of a Proto X-3 Bioenergy micro gas turbine for green building applications. The computational fluids dynamics (CFD) simulation was conducted in two dimensions, turbulent flow and gas phase combustion, with the goal of comparing the effects of different models in real conditions. Two different turbulence models, standard (STD) k-? and renormalization group (RNG) k-?, were applied for simulations. The fuel used was biogas produced from animal waste. Fuel consumption was assumed to be 100 kJ/s for simulations. The results of the simulations were analyzed and compared for reference. The temperature and the mass fraction of CH4, H2, O2, and CO2 distributions gave almost the same results for both models; therefore, both models (STD k-? and RNG k-?) could be used to represent the combustion process phenomenon without many significant differences."
