| Abstract: | A solution to the system of equations describing a cylindrical hybrid-aligned nematic liquid crystal is obtained. The rotational flow driven by vertical temperature gradient in such a cell is investigated theoretically. The cell is suggested as a new experimental setup for determining an additional relation required to measure the twelve thermomechanical coefficients. It is shown that the terms in the expressions for thermomechanical stress and heat flux obtained in 8] are equivalent to those originally proposed in 7]. |
