碩士 === 國立中興大學 === 應用數學研究所 === 82 === This study concerns with the influences of variable viscosity and internal heat generation on the onset of thermal stability with infinitely extensive fluid layer separated by a solid partition of finite thickness and thermal conductivity. The heated lower and cooled upper walls are isothermal and impermeable. We will use exponential model to impersonate the variable viscosity. The internal heat generation will be constrained its value in a particular range to sure both fluid layers and partition are heated from below. There are five dimensionless parameters for our system. Relative thickness of partition to fluid layers. The location of partition in fluid. Aspect ratio of thermal conductivity upon fluid and partition layers. The viscosity ratio at isothermal walls. Internal heat generation.
