Simultaneous heat and water
WebbThe Simultaneous Heat and Water (SHAW) model, originally developed to simulate soil freezing and thawing, simulates heat, water and solute transfer within a one-dimensional profile which includes the effects of plant cover, dead plant residue, and snow. WebbThe exploitation of thermal water as a heat source in houses and apartments (during winter) is a widely used alternative to natural gas. However, this type of water may contain organic contaminants, which must be removed before releasing the used water into …
