Calculation of Turbulence Kinetic Energy based on Image Light Stream Vectors and k-e Differential Equations
Analysis of the turbulence variation is a difficult topic in the fluid research. For the purpose of obtaining accurate parameters of turbulence motion, tracing particles be equally-distributed scattered into the flow field to reflect the turbulence motion locus, after each particles movement has been shot in continuous time-points, thus their absolute spatial coordinates can be determined. Combining with theory of image light stream vectors, these tracing particles motion velocities and vectors in each instantaneous moment can be deducted. According to the given boundary conditions and k-e differential equations the turbulence kinetic energy is calculated and its revised results are reached. Finally the direct measurement is used for verifying the calculated results accuracy and reliability. This experiment provides a new idea for following research of turbulences simulation and analogy.
