The purpose of this contribution is to derive a reduced-order two-phase flow model in- cluding interface subscale modeling through geometrical variables based on Stationary Action Principle (SAP) and Second Principle of Thermodynamics in the spirit of [6. 14]. The derivation is conducted in the disperse phase regime for the sake of clarity but the resulting paradigm can be used in a m... https://www.houseandholders.shop/product-category/napkins/
