... is the temperature, and r is the distance. Typical values for d σ /dT range from approximately −0.3 × 10 −3 N/m-K for a pure metal or 0.36 × 10 −3 N/m-K (note the sign change) when a surface-active element is adsorbed on the surface ( Ref 9 ). The flow is driven from the area of low surface tension toward...
