This presentation discusses the new follower plate design. Details include the CFD simulation results and how they were used in the design process, as well as the experimental tests used to validate the simulations. The CFD models provided some unexpected data that was used to greatly reduce residence time of the adhesive inside the follower plate, as well as decrease the temperature range of the adhesive as it flows from the follower plate into the pump. 25 different CFD models were created in the design process. The resulting model and design contained 24 one-inch radially drilled holes. This resulted in a much greater flow passage from the fins to the inlet of the pump. Fins were placed uniform distances apart from one another. Understanding where the majority of heat transfer was occurring allows the fins to be matched to the shape of the drum's bottom, providing an increase of approximately one gallon of useable volume per drum. The CFD models provided data that allowed for a 44 percent increase in the flow rate of the hot melt butyl adhesive.
