“…This has been conveyed in previous studies where the occurrence of backflow indicates a low heat transfer rate that occurs [8]. So it can be concluded that adding VG type common flow up and common flow down can delay the occurrence of backflow in the downstream tube.…”

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.

“…The main data validated in each component are thermal data regarding temperature (T), enthalpy (h), pressure (P), and mass flow rate (m). These simulation results are quite acceptable when compared with similar studies using Cycle Tempo [18]. The actual power plant data is taken when the power plant is working at a load of 180 MW.…”

Condenser is a type of heat exchanger that serves as condensation for turbine output steam. In general, a steam power plant uses a surface condenser. This type of condenser is a type of shell and tube. Condensers have a phenomenon of convection heat transfer. The change in distance between condenser tubes is one way to increase the rate of heat transfer. To produce maximum heat transfer, it can be determined by the variety of distances between tubes. The research was conducted by analyzing the flow characteristic and heat transfer around condenser tube banks with gap ratio variation (s/d), which compares transverse distance (ST ) and tube diameter (d) with variations of 3.2, 2.7, 2, and 1.7. 2-dimensional simulation with Computational Fluid Dynamics (CFD) is a numerical method and algorithm for solving and analyzing problems that occur in fluid flows. Based on the results obtained, the smaller the Gap Ratio, the lower the outlet temperature produced and the maximum heat transfer, but the pressure drop value obtained the bigger. Also, the smaller Gap ratio, the bigger v max produced. The lowest outlet temperature value at the variation of 1.7 is 310.66 K, and the coefficient of heat transfer is 103.34 W/m2K. Pressure drop produced at variation 1.7 is 515.99 Pa. Variation 2 is the best gap ratio variation, seen from the heat transfer result and the pressure drop value is not too large. The coefficient heat transfer and pressure drop in variation 2 are 76.95 W/m2K and 119.17 Pa.
