Evaluation of Flow Characteristics of Fluids in a Microperfusion Cell by Means of Finite Element Analyses

In order to study the mixing of two liquids in a reaction chamber finite element analyses have been conducted. Different operating conditions like the filling of the empty reaction cell with liquids, mixing of fluids with different doping concentrations have been analyzed in dependence on varying flow velocities of liquids. To verify the results of simulation a reaction cell has been built up using LTCC-technology (low temperature cofired ceramic). Top and bottom side of the reaction cell were covered with a glass plate which enables the optical inspection and analyses of the sequence of mixing of coloured liquids.
