This dataset comprises a comprehensive collection of videos and images illustrating the fluid dynamics swallowing aspiration in patient-specific pharyngolaryngeal model with varying epiglottis angles. The data also includes physical properties fluids used, comprising dynamic viscosity, surface tension, contact angle. Videos under conditions were collected to investigate mechanisms underlying aspiration. study utilized biomechanical developed using transparent casts an anatomically accurate structure. Fluorescent dye was used visualize liquid flow from both side back views. for two types liquids, water 1% w/v methylcellulose aqueous solution, evaluated dispensing speeds (fast slow) locations (anterior posterior) across four angles (30° up-tilt, 0° horizontal, 45° down-tilt, 80° down-tilt). Additionally, photos setup, models STL files 3D models. document distinct patterns frequent sites identified during experiments, including interarytenoid notch, cuneiform tubercular recess, vallecula. These are valuable researchers aiming understand etiology dysphagia can be reused validate computational models, guide future experimental designs, inform clinical diagnostics treatment strategies. is organized into folders based on angles, speeds, locations, as well types. organization facilitates easy access analysis biomedical engineering, research, biology. provide rich resource further investigation mechanics development etiology-based interventions management.
