Partially penetrating wells:. aquifer is so thick that a fully penetrating well is impractical. Increase velocity close to well and the affect is inversely related to distance from well (unless the aquifer has obvious anisotropy). Heat Transfer . is the transport of . thermal energy. due to a temperature difference across a . medium(s. ). mediums: gas, liquid, solid, liquid-gas, solid-gas, solid-liquid, solid-solid, etc..
