Abstract Scope Using a specific description of the heat transfer, and diffusion coefficients, general mass transfer theory is applied to data available in the literature to identify their respective dissolution rate. The following calculations using data from the literature are then compared to experimental work performed under laboratory conditions using a gravimetric method to evaluate the dissolution rate of alumina disks. The contrast between the data from our experimental work and the validation provided by the literature is assumed inherent to the morphology of the sample and the adequate description of the flow around it. The following discussions highlight the dominant factor affecting the mass transfer coefficients and pinpoint the theoretical challenges to overcome to achieve more precise relations for future works.
