Akhirnya “Blue Arrow”, Suzuki GSXR150 Datang Juga, Menemani Klan DOHC
Assalamu’alaikum wa rochmatullohi wa barokatuh
Salam sejahtera buat kita semua, semoga kita semua selamat di perjalanan sampai ke tujuan
Setelah lebih dari satu bulan menuggu, akhirnya jagoan baru suzuki gsx r150 datang juga. Surprise juga melihat warna biru gsx r150, yang beda dengan warna biru kebanyakan. Terutama yang sering ane lihat pada r15 movistar. Apalagi gsx r150 warna biru jarang…

ABSTRACT Autonomous Underwater Vehicles (AUVs) are robots able to perform tasks without human intervention (remote operators). Research and development of this class of vehicles has growing, due to the excellent characteristics of the AUVs to operate in different situations. Therefore, this study aims to analyze turbulent single fluid flow over different geometric configurations of an AUV hull, in order to obtain test geometry that generates lower drag force, which reduces the energy consumption of the vehicle, thereby increasing their autonomy during operation. In the numerical analysis was used ANSYS-CFX® 11.0 software, which is a powerful tool for solving problems involving fluid mechanics. Results of the velocity (vectors and streamlines), pressure distribution and drag coefficient are showed and analyzed. Optimum hull geometry was found. Lastly, a relationship between the geometric parameters analyzed and the drag coefficient was obtained. KEYWORDS AUV, Hull, Drag Coefficient, Numerical Simulation
REGARDING THE AERODYNAMICS OF BICYCLES Are they a good alternative to fossil fuel powered transport? Â
Tom Murphy, at Do the Math, notes:
A generic shape not designed with aerodynamics in mind—let’s call it a man-bear-pig—will have a drag coefficient around 0.8–1.4. Â
A trout, on the other hand, has a drag coefficient around 0.1. !!
What we really need is a trout on a bicycle! Then we’d really be smokin’.  ... a bicycle really screams out to have a fish ride it!Â
Btw, the really artistic fish-on-a-bicycle is from/by i cant think of a cool blog title. Â And the GIF is from Jenny's Wounded Knee blog
