Published on


This is one of a set of experiments designed for lower level undergraduate courses that incorporates novel thin films for drug delivery. The focus of the experimental set is to introduce pharmaceutical concepts to undergraduates while also incorporating general engineering educational objectives.   This contains both a student version and instructor version.

In this lab, students are introduced to basic concepts of fluid dynamics, specifically, the viscosity of a fluid.  The students investigate whether a commercial dressing is a Newtonian or non-Newtonian fluid based on viscosity readings taken via a viscometer at various RPM’s.  The main objectives of this experiment are:  Students will learn how about viscosity and viscosity enhancement chemicals; Students will clearn how to use a viscometer; Students will learn to create and analyze an empirical model.

This experiment (and the others in this set) was developed by Rowan University as part of the NSF-funded Engineering Research Center (ERC) for Structured Organic Particulate Systems (SOPS).
