报告摘要(ABSTRACT):
This research intends to present a numerical method for solving a real application problem in the fluid dynamic fields characterized by a stochastic inverse models. The sparse observations, noisy measurements, and highly nonlinear,  non-Gaussian  properties, etc. of the real problems lead to the complicated representation of the stochastic inverse solutions. To incorporate the observation data and PDE model, a probabilistic solution is constructed by the objective Bayesian inferences framework. To efficiently deal with high-dimensional properties and accelerate the numerical simulations, some advanced computational techniques in the fields of uncertainty quantity, PDE constrained optimal control, etc. are combined together. Finally, the numerical tests are presented.
