Research Projects

In a variation on the countercurrent vapor-liquid contacting unit operation the vapor flows horizontally at right angles, or crossflow, to the liquid. The advantages are low pressure drop in the column & greater vapor flow rates without flooding. Applied to air stripping of groundwater, it allows low volatility organics to be successfully stripped. Dr. Wetzel's research centers on the modeling & application of this process. Wetzel is working with faculty & students in the LSU School of Forestry on the modeling of wood drying processes. The standard engineering analysis must be expanded since the diffusion coefficient changes with the wood's moisture content & the grain direction. A number of external factors influence the boundary conditions.
