high pressure shaft seals.
The design must be such that it balances the need for a tight seal with the amount of friction generated during operation. Excessive friction can lead to wear and heat buildup, while insufficient sealing can allow fluid leakage. Therefore, engineers carefully select materials and dimensions to ensure optimal performance.
The efficiency of a gas heat exchanger is governed by various factors, including temperature difference, flow arrangement (counterflow, parallel flow, or crossflow), and the material properties of the heat exchanger itself
. For instance, counterflow arrangements, where the two fluids move in opposite directions, typically yield higher efficiency compared to parallel flow arrangements. This is due to the greater temperature gradient maintained across the heat exchanger, which facilitates more effective heat transfer.
