- The purpose of this thesis is to understand the effect of pipe curvature on heat transfer inparticle-laden flow. Extensive research has been conducted on fluid flow with particleentrainment, providing a strong foundation for understanding the parallel between theoreticalmodels and experimental results. The thesis begins by providing insight into previous research toexhibit the reasoning of conducting this new research. Then, it discusses the experimentalmethods used to entrain particles in a gaseous flow through a heat exchanger and the proceduresto gather data from this system. In these experimental tests, nitrogen gas is flowed through halfinchdiameter stainless steel piping and entrained with copper powder. Heat tape is used to heatthe test sections and provide a constant heat flux boundary condition for heat transfer. Analysisof the experimental data showed trends that curvature increased the Nusselt number by up to300% in some cases compared to the equivalent straight-pipe experiment. Further, for a curvedheat exchanger, the heat transfer was higher along the outer curve of the pipe compared the innercurve, likely due to secondary flow effects. Finally, the presence of the particles in gaseous flowincreased the heat transfer in the system compared to gas-only flow, as evidenced by thedecreased temperature differences between the wall temperatures and the bulk flowtemperatures. The present research suggests significant heat transfer benefits are possible withcurved-pipe, particle-laden flows.
