AB-10-C034 -- Understanding of flow and scalar fields by combining Measured Data and CFD PDF

A cost function expressed by the remainders of the governing equations and the difference between observed values and the solutions was proposed. This method was applied to a two-dimensional room and the performance of the cost function method was examined. The individual-type solution, in which the governing equation of a variable is partially differentiated with respect to itself, was compared with the integrated-type solution, in which the governing equation of a variable is partially differentiated with respect to another variable. The integrated-type solution, by combining the data of temperature, concentration and wind components, gave better results for all the variables than the individual-type solution.
