Development of a robust numerical model using cfd approach to analyse the flow characteristic inside a cyclone separator / Khong Jun Yong
Simulasi menggunakan teknik CFD telah dijalankan untuk menganalisis ciri-ciri aliran dalam pemisah siklon dalam empat halaju masuk yang berbeza, iaitu 7ms−1,13𝑚𝑠−1,16𝑚𝑠−1,𝑎𝑛𝑑 22𝑚𝑠−1. Data eksperimen yang digunakan dalam pengesahan simulasi telah diperolehi daripada kesusasteraan. Ideal y+ telah dikawal dengan pengiraan ketebalan lapisan pertama dan pengesahan grid telah dilakukan. K epsilon RNG and Reynolds Stress Model telah digunakan untuk mensimulasikan model. Kajian ciri-ciri aliran telah dilakukan dalam keadaan fana dengan model yang tegap. Profil dan kountur menunjukkan halaju magnitude vector, kepusaran, tekanan static, tenaga kinetic bergelora, dan RMS untuk turan naik halaju bergelora. Model RSM digunakan kerana percanggahan dari segi kejatuhan tekanan static berkurang. Aliran udara dalam pemisah siklon adalah sangat bergelora dan kelakuan aliran udara boleh diperhatikan dengan jelas. _______________________________________________________________________________________________________ Simulation using computational fluid dynamic techniques were performed intending to analyze the flow characteristic inside a cyclone separator in four different inlet velocities, 7ms−1,13𝑚𝑠−1,16𝑚𝑠−1,𝑎𝑛𝑑 22𝑚𝑠−1. The experimental data used in validation of simulations were obtained from the literature. Ideal y+ is controlled with the calculation of first layer thickness and grids verification is done. K-epsilon RNG and Reynolds Stress Models are used to simulate the model. Flow characteristic study is done in transient state with a developed robust numerical model. Profiles and contours show velocity magnitude vector, vorticity, static pressure, turbulent kinetic energy, and RMS of turbulent velocity fluctuation. RSM model is used results in less discrepancy in term of static pressure drop. The air flow inside the cyclone separator is highly turbulent and air flow behaviour is clearly observed.
