diaspirasi

Diaspirasi is a term that refers to the process of a liquid or gas being absorbed into or diffusing through a porous solid. This phenomenon is common in various natural and industrial processes. For example, in nature, diaspiration plays a role in how plants absorb water through their roots and how nutrients are transported within soil. In industrial applications, diaspiration is crucial in processes like filtration, where liquids are passed through porous membranes, or in the drying of materials, where moisture diffuses out of the solid.

The rate of diaspiration is influenced by several factors, including the properties of the porous solid, such as pore size, distribution, and connectivity, as well as the characteristics of the fluid, like viscosity and surface tension. The pressure gradient across the solid also plays a significant role, driving the fluid into or out of the pores. Understanding diaspiration is essential for optimizing processes in fields such as chemical engineering, material science, and environmental science, where controlling the movement of fluids through solids is often a key objective. The study of diaspiration often involves principles of fluid dynamics and mass transfer.
