51. Micro Channel Heat Transfer, Pressure Drop and Macro Prediction Methods
Published: 6/1/2003
Author: Mark A Kedzierski
Abstract: Advances in the basic understanding of fluid physics have opened an era of unprecedented application of heat transfer processes, and fluid dynamics systems using micro channels. One of the greatest obstacles to the application of leading edge fluid p ...

52. A Semi-Theoretical Model for Predicting Refrigerant/Lubricant Mixture Pool Boiling Heat Transfer
Published: 5/1/2003
Author: Mark A Kedzierski
Abstract: This paper outlines the development of a semi-theoretical model for prediction the pool boiling heat transfer of R123/lubricant mixtures on a roughened, horizontal flat pool-boiling surface. The predictive model is based on the mechanisms involved i ...

53. Condensation (Chapter 15)
Published: 1/1/2003
Authors: Mark A Kedzierski, J C Chato, T J Rabas
Abstract: Condensation is the process by which a vapor is converted to its liquid state. Because fo the large internal energy difference between the liquid and vapor states, a significant amount of heat can be released during the condensation process. For this ...

54. A Generalized Pressure Drop Correlation for Evaporation of Alternative Refrigerants in Micro-Fin and Smooth Tubes
Series: NIST Interagency/Internal Report (NISTIR)
Report Number: 6333
Published: 10/1/2001
Authors: J Y Choi, Mark A Kedzierski, Piotr A Domanski
Abstract: This paper presents a pressure drop correlation for evaporation and condensation in smooth and micro-fin tubes. The correlation was developed from a data base consisting of the following pure and mixed refrigerants: R125, R134a, R32, R410A (R32/R125 ...

56. Effect of Bulk Lubricant Concentration on the Excess Surface Density During R123 Pool Boiling
Series: Journal of Research (NIST JRES)
Published: 7/1/2001
Author: Mark A Kedzierski
Abstract: This paper investigates the effect that bulk lubricant concentration has on the non-adiabatic lubricant excess surface density on a roughened, horizontal flat pool-boiling surface. Both pool boiling heat transfer data and lubricant excess surface den ...

57. Use of Fluorescence to Measure the Lubricant Excess Surface Density During Pool Boiling
Series: NIST Interagency/Internal Report (NISTIR)
Report Number: 6727
Published: 1/1/2001
Author: Mark A Kedzierski
Abstract: This paper presents what are believed to be the first measurements of the non-adiabatic lubricant excess surface density on a roughened, horizontal flat pool-boiling surface. Both pool boiling heat transfer data and lubricant excess surface density ...

58. Refrigerant/Lubricant Mixture Boiling Heat Transfer Research at NIST
Published: 9/1/2000
Author: Mark A Kedzierski
Abstract: This paper overviews the boiling heat transfer research of the recent few years at NIST (National Institute of Standards and Technology) on refrigerant/lubricant mixtures. The aim of the research was to fundamentally understand the effects of lubric ...

59. Evaporation and Condensation Heat Transfer Performance of Flammable Refrigerants in Brazed Plate Heat Exchangers
Series: NIST Interagency/Internal Report (NISTIR)
Report Number: 6541
Published: 7/1/2000
Authors: Mark A Kedzierski, J C Chato, T J Rabas
Abstract: Measured overall Nusselt numbers were determined for R22, R290, R290/600a, and R32/152a undergoing evaporation and condensation in a brazed plate heat exchanger. The refrigerants experienced wavy, stratified flow at low heat and mass fluxes, 1.3 to ...

60. The Effect of Lubricant Concentration, Miscibility, and Viscosity on R134a Pool Boiling
Series: NIST Interagency/Internal Report (NISTIR)
Report Number: 6450
Published: 1/1/2000
Author: Mark A Kedzierski
Abstract: This paper presents pool boiling heat transfer data for twelve different R134a/lubricant mixtures and pure R134a on a Turbo-BIITM-HP surface. Themixtures were designed to examine the effects of lubricant mass fraction, viscosity, and iscibility on ...
