Heated particle-laden layer
= Heated particle-laden layer
A dilute <particle suspension> can supply both excess <mass density> and heat. To first order its <equation of state> is $\rho/\rho_0=1+\gamma\phi-\theta$, where $\phi$ is the <particle volume fraction> and $\theta$ is fractional <thermal expansion>. <Particle deposition flux> reduces $\phi$, while particle heating increases $\theta$. The competition can reverse the <reduced gravity> and create <unstable density stratification>.
