Implicit Finite Difference

The purpose of this study is to analyze the combined heat and mass transfer through condensation of volatile organic compounds (VOCs), particularly alcohol (n-butanol-propanol) in the presence of non-condensable gas inside a vertical tube. An implicit finite difference method is employed to solve the coupled governing equations for liquid film and gas flow together with the interfacial matching conditions. The numerical results indicate that the Transfers are more intense at the entrance of the tube for the ternary mixture and promote heat and mass exchanges.

Flow Distributor

The reduction of harmful substances emission into the atmosphere is very important to create compact, energy-efficient catalytic units for afterburning volatile organic compounds. A key component of such units is the catalyst cartridge. The efficiency of its operation is provided by the supply of a gas flow with a uniform velocity field. To solve the problem, the gas flow distributor and an aerodynamic stand for its testing were created. A set of air-flow blades was used to align the velocity profile before the catalyst cartridge. Also flow kinematics inside the cartridge was investigated via laser Doppler anemometry method.
