  • NEFCO™ Awarded new patents case study

    NEFCO™ has been granted two new patents for its Dual Surface Baffle System. The Dual Surface Baffle was developed from work done as a part of NEFCO’s on-going Computational Fluid Dynamics (CFD) Density Current Baffle Study. The first, US Patent No. 7,556,157, describes a Dual Surface Baffle with a curved lower baffle segment. The second, US Patent No. 7,726,494, describes a Dual ...

  • NEFCO’s CFD study case study

    The study was originally conceived to evaluate the performance of the NEFCO Stamford Baffle design and several variations on that design to better understand the parameters that affected baffle performance. To that end, the plan was straightforward. The first step was the simulation of a 70-ft diameter clarifier. This clarifier would serve as the test bed to calculate the predicted effectiveness ...

  • Second law analysis of transient heat transfer for turbulent flow in a circular tube with baffle inserts

    This paper presents the results of an experimental investigation of transient forced convective heat transfer for turbulent flow of nine circular tubes with baffle plate inserts using different pitch to tube inlet diameter ratios and baffle orientation angles in the range of Reynolds number 3000≤Re≤20000 in the case of constant heat flux. The characteristic parameters of the tubes are: pitch to ...
