The Non-Homogeneous Wave Equation in Non-Cylindrical Domains
Trends in Computational and Applied Mathematics, 2001 We prove the existence and uniqueness of a global regular solution to the mixed problem for the nonhomogeneous wave equation in a noncylindrical domain using a hiperbolic nonsingular smooth transformation of the original problem to a nonlinear hyperbolic

The wave equation with internal control in non-cylindrical domains
Advances in Difference Equations, 2017 In this paper, we shall be concerned with interior controllability for a one-dimensional wave equation in a domain with moving boundary. When the speed of the moving endpoint is less than a certain constant which is less than the characteristic speed, we

Exact controllability problem of a wave equation in non-cylindrical domains
Electronic Journal of Differential Equations, 2015 Let $\alpha: [0, \infty)\to(0, \infty)$ be a twice continuous differentiable function which satisfies that $\alpha(0)=1$, $\alpha'$ is monotone and ...

Throat length effect on the flow patterns in off-design conical nozzles [PDF]
FME Transactions, 2022 In the present work, a flow field study was performed for off-design conical nozzles with non-circular cylindrical throat sections such as those found in experimental sounding rocket motor applications. The flow field was simulated with the RANS model in

Weak solutions of parabolic equations in non-cylindrical domains [PDF]
Proceedings of the American Mathematical Society, 1997 In their classical work, Ladyzhenskaya and Ural ′ ’ tseva gave a definition of weak solution for parabolic equations in cylindrical domains. Their definition was broad enough to guarantee the solvability of all such problems but narrow enough to guarantee the uniqueness of these solutions.
