Abstract
Official abstract text for this publication.
Method for determining wettability of porous materials comprises placing a sample of a porous material into a cell of a calorimeter and contacting the sample with a wetting fluid. A heat flow into the cell is continuously measured. Based on results of the measurement and taking into account a thermal effect of the fluid compression, a first wetting contact angle of pores filled with the wetting fluid is calculated. Then, a pressure in the cell containing the sample is increased starting from an initial value until pores of the sample are completely filled with the fluid. Then, the pressure is reduced to the initial value while continuously measuring of a heat flow into the cell. The method enables calculation of a second wetting contact angle for pores completely filled with the fluid and of a third wetting contact angle for pores free from the fluid.
First claim
Opening claim text (preview).
What is claimed is: 1. A method for determining wettability of porous materials comprising: placing a sample of a porous material into a calorimeter cell, contacting the sample with a wetting fluid and continuously measuring a heat flow into the cell, calculating a first contact wetting angle of pores partially filled with the wetting fluid due to spontaneous impregnation of a porous space of the sample at a constant pressure based on results of the heat flow measurement and t…
