title = "Liquid flowing downward in parallel pipes with evaporation",
abstract = "Two basic flow patterns are possible for evaporating liquid flowing downwards in a vertical pipe: co-current downward flow of liquid and gas and counter current flow where the liquid flows downward while the gas flows in the upward direction. For an assembly of parallel pipes with a common upper plenum and a common bottom manifold numerous different flow configurations can take place within the parallel pipes. Analysis of the various flow configurations is presented. The analysis contains steady state solutions, stability analysis and transient simulations. Specific examples for single and two parallel pipes are detailed. The analysis is restricted to low flow rates and low heat fluxes where it is possible to obtain counter current gas liquid flow. It is shown that for parallel pipes many of the steady state solutions are unstable. The transient simulations are consistent with the linear stability analysis.",
