Analysis of the fluid-dynamic and thermal behaviour of a tin bath in float glass manufacturing
TL;DR: In this paper, the authors studied the fluid-dynamics and thermal behaviour of the tin bath from both theoretical and experimental viewpoints, and showed the existence of a flow in the opposite direction to that of the advance of the ribbon, whose features depend on operating conditions such us glass thickness and the manufacturer's practice of using baffles.
