Abstract
Studies have proved that the mucilage of Aloe vera is a good polymeric additive to be used as drag reducer in turbulent flows, besides being natural and easy to obtain. However, there are many varieties of the plant. This work evaluates two different species of the plant, Aloe arborescens and Aloe barbadensis, in order to verify if there is any difference in their capacity to reduce the friction factor in the transport of fluids. In order to achieve this objective, it was necessary to plant and cultivate the plants in similar conditions and a specific methodology for extraction of the concentrated mucilage was followed. The rheological characterization was done using a rheometer, in which the drag reduction tests were also performed. The results show that the species Aloe arborescens has higher efficiency in reducing the flow resistance than Aloe barbadensis.
