  abstract: This dissertation describes a three-dimensional numerical
  abstract: model for simulation of turbulent flow and heat transfer
  abstract: inside shell-and-tube heat exchangers. The simulation is
  abstract: based on a distributed resistance method that uses a modified
  abstract: k-E turbulence model. It is assumed that all shellside fluid
  abstract: within a computational cell has the same velocity and
  abstract: temperature. Volume porosities and surface permeabilities
  abstract: account for tubes, nozzles, and an arbitrary arrangement of
  abstract: baffles. Sub-models are described for shellside pressure
  abstract: drop, turbulence generation and dissipation by tubes, baffle-
  abstract: shell and baffle-tube leakage, shellside and tubeside heat
  abstract: transfer. These submodels use parameters that have not been
  abstract: altered from their published values. Geometry generators are
  abstract: outlined for tubes, baffles, and nozzles. The numerical
  abstract: model is validated by comparison with standard benchmarks and
  abstract: with experimental data for shell-and-tube heat exchangers
  abstract: from the University of Delaware (Bell, 1963) and Argonne
  abstract: National Labs (Halle et al., 1984). Good agreement (relative
  abstract: error in overall pressure drop is less than 10% and relative
  abstract: error in temperature differences is less than 15%) is
  abstract: obtained between the computations and experiments. All
  abstract: validations were performed for E type shells. J, F, and H
  abstract: shells can be handled, but were not validated. The model can
  abstract: represent single segmental baffles of any baffle cut and
  abstract: baffle spacing. Double and triple segmental baffles, and
  abstract: disk and donut baffles are not represented in the model.
  abstract: Currently plain tubes in a staggered or inline configuration
  abstract: can be represented by the numerical model. Finned tubes are
  abstract: not modeled. It is assumed that the tubes are clean (no
  abstract: fouling). Single tube pass parallel flow or counter flow
  abstract: arrangements and a U tube bundle are modeled. Multi-tube
  abstract: pass arrangement with mixing at the end of a tube pass is not
  abstract: modeled. Further work needs to be done to represent
  abstract: impingement plates. Since all flow calculations performed
  abstract: were in the turbulent regime, effect of property variation on
  abstract: pressure drop and heat transfer was not considered. After
  abstract: validation, the numerical model is used to analyze three
  abstract: dimensional flow, pressure, temperature, and turbulence
  abstract: fields, within shell-and-tube heat exchangers. The computed
  abstract: flow and turbulence fields show a reasonable behavior.
