Named after the physicist Jean Baptiste-Biot (1774-1862), the Biot number is a unit-less/dimensionless number used in problems dealing with heat transfer. The Biot number allows for the calculation of a ratio between the heat transfer resistances within a system and the surroundings of the system, as well as its surface.

Poroelasticity is a field in materials science and mechanics that studies the interaction between fluid flow and solids deformation within a linear porous medium and it is an extension of elasticity and porous medium flow (diffusion equation). The deformation of the medium influences the flow of the fluid and vice versa. The theory was proposed by Maurice Anthony Biot (1935, 1941) as a theoretical extension of soil consolidation models developed to calculate the settlement of struct…
