N2 - Heat Recovery Steam Generator (HRSG) is a crucial component in the combined cycle power plant, which utilises gas turbine exhaust gases to heat water into further hot steam. Research is needed to improve the heat transfer process in the LP Evaporator. One way to increase the heat transfer is by adding a Vortex Generator (VG) to the LP evaporator. The Vortex Generator itself is a vortex generator that aims to make the fluid flow from the gas turbine not only hit the tube banks in the HRSG but also between the tubes installed a Vortex Generator, which functions to make the fluid flow that was previously laminar into turbulent so that the heat transfer that occurs in LP Evaporator just got better. The analysis consists to velocity contour, temperature contour, local Nu, heat transfer (q), and pressure drop. To determine fluid flow using 2D simulation with Computational Fluid Dynamics (CFD). From the geometry type. Variations made are geometric shapes and the VG arrangement, namely rectangular common flow down, delta winglet common flow down, delta winglet common flow up, and rectangular common flow up. The heat transfer rate value is 2271.34 W, 2333.27 W, 3340.334 W, 3090.747 W. The highest heat transfer rate value occurs on the delta winglet with the common flow up arrangement, and the lowest heat transfer rate value occurs on rectangular with the common flow down arrangement.
