Moving droplets: The measurement of contact lines

Contact lines are the locations where a gas, liquid and a solid meet. From everyday experience we know that such contact lines can be mobile, for example in the case of a water droplet sliding over a glass surface. However, the continuum description of the flow towards or away from a contact line implies that the forces diverge as one approaches...

Experimental and numerical investigations on the flow field inside pre-and post-surgery models of posterosuperior septectomy

Three physiological functions of nasal breathing (air-conditioning, filtering and smelling) are closely related with airflow characteristics in the human nasal airway. Since fluid mechanical properties are heavily affected by the geometry of flow passage, the changes in anatomical shape of nasal cavity by disorders or surgical treatments alter...
