| الملخص: | Convection is a phenomenon widely observed in nature. To study the phenomenon
of convection in a laboratory scale is commonly used fluid observation
device. This device uses a fluid system, which is heated from below, that is called
Rayleigh-Benard Convection (RBC). Silicone oil as the fluid mixed with grinding
paste was put in a cylindrical chamber with an aspect ratio L = 10=1. Temperature
difference between the bottom plate and the top plate is represented by the control
parameter , which is = (T � Tc)=Tc. The observation results show that the
system is in a steady state at < 0, and it starts unstable at > 0 that phenomena
of convection begin to occur. Increasing the value of is followed by transitions of
thermal convection patterns on the fluid surface. Homogeneous raft which is floated
on the fluid surface is then observed and it is found the dynamics raft motion that are
linear and oscillatory motions. |
