英语翻译Estimating a three-dimensional flow from two-dimensional

英语翻译
Estimating a three-dimensional flow from two-dimensional imagery has its complications,and the method proposed below is intended to provide a solution which demonstrates a capability while not becoming too computationally costly.Research regarding flow fields and turbulence has been conducted,and aspects of that research have been applied to this work where applicable and possible.In attempting to combine flow estimations with effluent concentrations to determine a mass flow rate,this work forces inspection of the plume near stack exit.This area presents some unique problems when attempting to estimate a flow velocity using a temporal cross-correlation method which is dependent on brightness fluctuations.11–15 As described in the theory section below,certain assumptions and simplifications are made about regions of the flow in this research in order to support the development of a manageable method and to demonstrate the viability of IFTS as a flow rate characterization option.
