Engineering/Heat Exchanger10 DROPWISE CONDENSATION (액적응축) DROPWISE CONDENSATION (액적응축) "Dropwise condensation(액적응축)"은 수증기가 냉각되어 액체 상태로 응결될 때, 그 물방울이 표면에서 증발하지 않고 떨어져 나가는 현상을 나타낸다. 일반적인 응축 현상에서는 물방울이 표면에 머물러 있거나 유지되는 것이 일반적이지만, 액적응축에서는 물방울이 형성되고 빠르게 떨어져 나가는 특징이 있다. Dropwise condensation(액적응축)은 높은 열 전달 효율을 가진 기술적인 솔루션 중 하나로 간주되며, 열 교환 과정에서의 에너지 손실을 최소화하고 시스템의 효율성을 향상시키기 위해 연구 및 응용 분야에서 중요한 주제 중 하나이다. 액적응축이 막응축의 경우에 비해 큰 열전달 성능이 기대됨 액적응축을 구현하려면 열교환 표면의 We.. 2024. 2. 16. Transition Boiling Regime The transition boiling regime is probably the least studied region of the boiling curve because: (1) transition boiling is less important, practically speaking, than nucleate boiling, and (2) the mechanism of transition is very complicated and experimental investigation is very difficult. In this region, the liquid periodically contacts the heating surface creating large amounts of vapor and for.. 2022. 8. 18. Shell-and-Tube Heat Exchangers Construction Details The shell-and-tube heat exchanger is named for its two major components – round tubes mounted inside a cylindrical shell. The shell cylinder can be fabricated from rolled plate or from piping (up to 24 inch diameters). The tubes are thin-walled tubing produced specifically for use in heat exchangers. Other components include: the channels (heads), tubesheets, baffles, tie rods & spacers, pass pa.. 2014. 7. 17. TEMA 9th Edition RCB-4.6 : Impingement Baffles and Rrosion Protection Additionally, the NORSOK P-100 Process Standards for Offshore applications state: "Typically the following maximum inlet momentum for the inlet stream should be used on scrubbers: No inlet device: Rho * V2 2013. 12. 4. TEMA Standard for Tube Vibration TEMA STANDARDS Section.5 RCB-4.56 TUBE BUNDLE VIBRATION Shell side flow may produce excitation forces which result in destructive tube vibrations. Existing predictive correlations are inadequate to insure that any given design will be free of such damage. The vulnerability of an exchanger to flow induced vibration depends on the flow rate, tube and baffle materials, unsupported tube spans, tube .. 2013. 12. 4.
