Fathan Akbar, Elfi Yuliza, Nadya Amalia +2
As if it has become a consensus that the slope of the granular heap is straight, and from that, an angle of repose is defined. However, closer inspection shows that the slopes are…
Experiment and Modeling of Rice Winnowing: Granular Segregation Method in Ancient Traditions
Rahmawati Munir, Handika Dany Rahmayanti, Riri Murniati +3
Rice winnowing is a process of separation of small and large rice grains by air flow practiced since the ancient human history especially in societies where rice is the main source…
Stability of Granular Tunnel
Elfi Yuliza, Nadya Amalia, Handika Dany Rahmayanti +4
We demonstrated the stability of tunnels made of granular matters is strongly dependent on the grain size, tunnel diameter, and water content in the granules. Larger tunnel radius,…
Bending of Sparklers
Mikrajuddin Abdullah, Shafira Khairunnisa, Fathan Akbar
A new equation is proposed to explain the curvature of spent sparklers. We found the state of a segment of the sparkler to depend strongly on the state of its spent segments. The e…
