Energy loss due to friction in fluid transportation was a serious energy efficiency problem. Then, calcium carbonate (CaCO3) comes as a solution to solve this issue. The use of CaCO3 in water flow through the pentagon spiral pipe was effective to create more efficient flow by promoting drag reduction (DR). This research aimed to optimize the pentagon spiral pipe geometry to promotes drag reduction by CaCO3. The analysis has been done by using Computational Fluid Dynamics (CFD) with Ansys Fluent 19.2 in a steady-state flow. The flow model of k-ε RNG (Renormalization Group) was adopted to analyse the pitch variation effect on the drag reduction in various Reynolds numbers. The results showed a strong dependence of the drag reduction on the pitch variation and Reynolds number. The Pentagon spiral pipe geometry can be optimized with modification in pitch according to the fluid application condition.
