The reaction process in methanol solvent can be deduced from the computational results with CPCM solvent model and the supermolecular handling, namely the reaction involves four steps in the methanol solvent. The nucleophilic addition of trimethylamine to acraldehyde generates an enolate. Nucleophilic attack of the enolate on the aldehyde forms the carbon-carbon bond, followed by the proton-transfer process and the further elimination generating the product and liberating the trimethylamine catalyst.

对于CH3OH对反应体系的影响,可以综合考虑CPCM溶剂模型及超分子模型下的研究结果,即CH3OH溶剂中反应按四步进行,催化剂三甲胺首先与丙烯醛发生亲核加成,生成的两性离子中间体与甲醛发生类似于Aldol的醛醇缩合,形成碳-碳键,之后发生分子内质子转移,最后经E1cb消除得到产物,并释放催化剂三甲胺。

The Frechet derivative of the cost function is determined via the solution of an adjoint partial differential equation, and the boundary shape is then modified in a direction of descent. This process is repeated until an optimum solution is approached. The advantage is that the cost function variation is independent of the flow field variation, with the result that the gradient of cost function with respect to arbitrary number of design variables can be determined without the need for additional flow-field evaluations. So each design cycle requires the numerical solution of both the flow and the adjoint equations leading to a computational cost roughly equal to the cost of two flow solutions.

虽然他们的研究成果大多数都可以在公开性文献上看到,但是其中一些具体的细节问题的处理方法却没有透露,比如:伴随方程如何离散求解才能减小最终梯度计算中的误差,使得设计过程有效地进行;伴随方程与流动方程的边界条件是不同的,如何合理地处理伴随方程的边界条件,才能推动设计过程朝着设计目标而发展;在减阻问题中目标函数如何定义,求解梯度的具体数学公式如何推导,如何通过数值方法来实现它们等。
