Webdivergence theorem to show that it implies conservation of momentum in every volume. That is, we show that the time rate of change of momentum in each volume is minus the ux through the boundary minus the work done on the boundary by the pressure forces. This is the physical expression of Newton’s force law for a continuous medium. WebThe theorem has proven that the two surrogates can be embedded in two isomorphic RKHS, by which we propose a novel method named Gaussian process on polynomial chaos basis (GPCB) that incorporates the PCE and GP.
