4/7/2024 0 Comments Water & steam condensersThe reason is that the steam cannot flow into the internal of upper tube bundle and the air fractions are higher in the upper tube bundle with the upper-lower cooling water flow path. For the original tube arrangement, the heat transfer with the lower-upper cooling water flow path is better than that with the upper-lower cooling water flow path. The simulations indicate that the cooling water flow path is important in large condensers. The results were used to analyze the streamline, velocity, air mass fraction and heat transfer coefficient distributions. The effect of the cooling water flow path on the flow and heat transfer in a double tube-pass condenser for a 660 MW power plant unit was numerically investigated based on a porous medium model.
