  abstract: Since its discovery in 2004, graphene has been tipped as the material that can boost various applications' development. Among the methods developed to produce graphene in large-scale is chemical vapour deposition (CVD). CVD is viewed as the most cost-efficient method besides having the potential to synthesize high-quality graphene. Despite this potential, it requires excellent control in various aspects, including fluid dynamics inside the CVD tube. Further studies need to be done especially near the substrate to understand further the effect of fluid dynamics on the graphene synthesis process via CVD. One of the subsidiaries of fluid dynamics near the substrate was the boundary layer thickness. This is the first layer where carbon needs to pass through to be at the substrate's surface. Changing the tilting angle is one of the ways to change the boundary layer thickness. In this study, the simulation was done for horizontal CVD with different tilting angle, and then graphene was synthesized in the lab based on the simulation results. This is to understand the effect of substrate tilting to the fluid behaviour inside the CVD tube and the graphene produce. The simulation was done using ANSYS® FLUENT where a 1m tube was divided into three sections which are the calm, heating and outlet section. A constant temperature of 1273K was supplied at the heating section wall, and the other two sections were exposed to room temperature. A substrate was placed in the heating section with a tilting angle of 8°,15°,30°,45°,60° and 75°. Based on the simulation at a 0° angle, the boundary layer thickness becomes thicker as the flow moves from the front to the rear of the substrate. For other tilting angles, the boundary layer thickness became thinner as the flow moved from the front to the end of the substrate. Higher tilting angle produced a thinner boundary layer, but the non-uniformity of the boundary layer thickness over the substrate surface also became more prominent. Tilted su…
