  1. 1 hari yang lalu · The simulation results suggest that the packed and spray direct-contact heat exchangers can offer high overall volumetric heat transfer coefficients. They are comparable to indirect-contact heat exchangers such as a finned tube heat exchanger that require large amounts of steel.

  2. 8 Ogo 2024 · Direct Contact Heat Exchangers Working Principle: In direct-contact heat exchanger, the hot and cold fluids come into direct contact with each other. Therefore, allowing for direct heat transfer without the need for a separating surface.

  3. 14 Ogo 2024 · Plate and frame heat exchangers stand out for their high thermal efficiency, making them useful in a variety of heat transfer applications. At the core of their efficiency is the unique design that employs a series of thin, corrugated plates (see Figure 1). These plates are arranged in a frame, creating multiple channels for fluids to flow through.

  4. 30 Jul 2024 · This study introduces an experimental investigation of a novel direct trend evaporative cooler based on a ground-air heat exchanger (GAHE) using porous clay vessels as an evaporation media...

  6. 6 Ogo 2024 · Calculation methods of heat and mass transfer processes in contact heat exchangers can be broadly divided into two types [2,3,4,5]. One type makes use of all equations describing heat and mass transfer processes occurring inside the device.

  7. 29 Jul 2024 · A heat exchanger is broadly defined as a device that transfers thermal energy from one fluid stream to another. There are several ways to accomplish this transfer, and the final heat exchanger selection will be based on several criteria, including performance, cost, and overall size and footprint.
