FINITE ELEMENT ANALYSIS OF FULLY-DEVELOPED TURBULENT TWO-PHASE SECONDARY FLOW FIELDS IN A TRIANGULAR CONDUIT
ABSTRAKT
A three-dimensional finite element computer code, FEMOTH (Finite Element Method of Thermal-Hydraulics), has been previously developed in order to study the multidimensional flow patterns and the turbulent structure of fully developed turbulent two-phase flows in triangular conduits. Due to a homogeneous secondary flow assumption, the FEMOTH code predicted identical streamlines for both phases. FEMOTH code has been upgraded by using nonhomogeneous secondary flow model to expand the capability in predicting turbulent flow structures in a triangular conduit. The FEMOTH-TF (Two Fluid) code, now predicted secondary flow patterns for fully-developed turbulent two-phase flows in a triangular channel. Sensitivity study shows that the turbulence and void distribution are very important parameters for the turbulent secondary flow structures in the channel.
