High tortuosity
Higher tortuosity or curviness retards mass transfer as it acts obstructively on the drug particles within the formulation. HVAC makes extensive use of tortuosity in evaporator and condenser coils for heat exchangers , whereas Ultra-high vacuum makes use of the inverse of tortuosity, which is conductivity, with … See more Tortuosity is widely used as a critical parameter to predict transport properties of porous media, such as rocks and soils. But unlike other standard microstructural properties, the concept of tortuosity is vague with multiple … See more Usually subjective estimation is used. However, several ways to adapt methods estimating tortuosity in 2-D have also been tried. The methods … See more Subjective estimation (sometimes aided by optometric grading scales) is often used.
