81. Calorimetric and Visual Measurements of R123 Pool Boiling on Four Enhanced Surfaces (NISTIR 5732)
Series: NIST Interagency/Internal Report (NISTIR)
Report Number: 5732
Published: 11/1/1995
Author: Mark A Kedzierski
Abstract: Pool boiling of R123 on four commercial enhanced surfaces was investigated both calorimetrically and visually. The four surfaces were: (1) Turbo-BII(TM) (2) High-Flux(TM) (3) GEWA-K(TM), and (4) GEWA-T(TM). The surfaces were either machined or solder ...

83. Effect of Inclination on the Performance of a Compact Brazed Plate Condenser and Evaporator (NISTIR 5767)
Series: NIST Interagency/Internal Report (NISTIR)
Report Number: 5767
Published: 11/1/1995
Author: Mark A Kedzierski
Abstract: This study experimentally quantified the change in heat transfer and pressure drop associated with tilting a compact brazed plate heat exchanger from the intended vertical position. Both clockwise and counterclockwise rotations within a plane perpend ...

84. Visual Measurement Technique for Analysis of Nucleate Flow Boiling (NISTIR 5519)
Series: NIST Interagency/Internal Report (NISTIR)
Report Number: 5519
Published: 10/1/1994
Authors: Mark A Kedzierski, J. M. Crowder, A. M. Jacobi, L. Zhang
Abstract: This report records a visual measurement technique for analyzing bubbles formed by nucleate flow boiling. The purpose of measuring these bubbles is to expand understanding the boiling process. By studying the behavior of these vapor bubbles, a better ...

85. Single-Phase Heat Transfer and Pressure Drop Characteristics of an Integral-Spine Fin Within an Annulus
Published: 6/1/1994
Authors: Mark A Kedzierski, M S Kim
Abstract: The laminar, single-phase heat transfer and friction characteristics of a porcupine-like surface (integral-spine-fin) within an annulus are presented. The heat-transfer coefficient was determined using a modified version of the Wilson Plot method on ...

89. Simultaneous Visual and Calorimetric Measurements of R11, R123, and R123/Alkylbenzene Nucleate Flow Boiling (NISTIR 4948)
Series: NIST Interagency/Internal Report (NISTIR)
Report Number: 4948
Published: 10/1/1992
Author: Mark A Kedzierski
Abstract: Bubble formation during horizontal flow boiling of trichlorofluoromethane (R11), 1,1-dichloro-2,2,2-trifluoroethane (R123) and two R123/alkylbenzene lubricant mixtures was investigated both visually and calorimetrically. The test fluid was pumped thr ...
