41. Horizontal Convective Boiling of Pure and Mixed Refrigerants Within a Micro-Fin Tube
Published: 10/4/2007
Author: Mark A Kedzierski
http://www.nist.gov/manuscript-publication-search.cfm?pub_id=905038

42. Effect of CuO Nanolubricant on R134a Pool Boiling Heat Transfer with Extensive Measurement and Analysis Details
Series: NIST Interagency/Internal Report (NISTIR)
Report Number: 7454
Published: 10/1/2007
Author: Mark A Kedzierski
Abstract: This paper quantifies the influence of CuO nanoparticles on the boiling performance of R134a/polyolester mixtures on a roughened, horizontal, flat surface. Nanofluids are liquids that contain dispersed nano-size particles. A lubricant based nanofluid ...

43. Effect of Lubricant on R410A Horizontal Flow Boiling
Series: NIST Interagency/Internal Report (NISTIR)
Report Number: 7456
Published: 9/27/2007
Authors: N N Sawant, Mark A Kedzierski, J S Brown
Abstract: The paper experimentally quantified the effect of lubricant on horizontal flow boiling of R410A. This was accomplished by first establishing a baseline by measuring the convective boiling heat transfer performance of pure R410A. The heat transfer ...

44. Effect of CuO Nanoparticle Concentration on R134a/Lubricant Pool Boiling Heat Transfer With Extensive Analysis
Series: NIST Interagency/Internal Report (NISTIR)
Report Number: 7450
Published: 9/20/2007
Author: Mark A Kedzierski
Abstract: This paper quantifies the influence of CuO nanoparticle concentration on the boiling performance of R134a/polyolester mixtures on a roughened, horizontal flat surface. Nanofluids are liquids that contain dispersed nano-size particles. Two lubricant ...

45. Effect of Refrigerant Oil Additive on R134a and R123 Boiling Heat Transfer Performance
Report Number: 7132
Published: 1/1/2007
Author: Mark A Kedzierski
Abstract: This paper investigates the effect that an additive had on the boiling performance of an R134a/polyolester lubricant (POE) mixture and an R123/naphthenic mineral oil mixture on a roughened, horizontal flat surface. Both pool boiling heat transfer da ...

46. Contamination and Decontamination of Building Plumbing Systems
Published: 9/25/2006
Authors: Stephen J. Treado, Mark A Kedzierski, Stephanie S Watson, Kenneth D Cole
Abstract: The quality of drinking water has always been a subject of interest. In fact, a stable and secure supply of clean drinking water is a hallmark of modern society. Recently, new concerns have arisen regarding the potential occurrence of intentional o ...

47. Development of a Fluorescence Based Measurement Technique to Quantify Water Contaminants at Pipe Surfaces During Flow
Series: NIST Interagency/Internal Report (NISTIR)
Report Number: 7355
Published: 9/1/2006
Author: Mark A Kedzierski
Abstract: This paper provides a detailed account of the development of a fluorescence based measurement technique for measuring the mass of contaminant on solid surfaces in the presence of water flow. A test apparatus was design and developed for the purpose ...

48. Influence of Concentration and Additives on R123/Paraffinic Material Oil Boiling Heat Transfer Performance (NISTIR 7336)
Series: NIST Interagency/Internal Report (NISTIR)
Report Number: 7336
Published: 9/1/2006
Authors: Mark A Kedzierski, D H Han
Abstract: This paper investigates the effect that oil concentration had on the boiling performance of an R123/paraffinic mineral oil mixture on a roughened, horizontal flat surface. For all compositions, the lubricant caused a heat transfer degradation relati ...

49. Report of Phase One Measurement and Analysis of Building Water System Contamination and Decontamination
Series: NIST Interagency/Internal Report (NISTIR)
Report Number: 7351
Published: 7/3/2006
Authors: Stephen J. Treado, Mark A Kedzierski, Stephanie S Watson, Dale P Bentz, Nicos Martys, Kenneth D Cole
Abstract: This report describes the results of the first phase of a research project to evaluate how contaminants accidentally or intentionally introduced into the water supply might accumulate in building plumbing systems, and how these contaminants might be ...

50. A Comparison of R245fa Pool Boiling Measurements to R123, and R245fa/Isopentane on a Passively Enhanced, Horizontal Surface
Published: 4/3/2006
Author: Mark A Kedzierski
Abstract: This study presents pool boiling heat transfer measurements for R245fa, R123 and a mixture of R245fa and isopentane on a flattened passively enhanced low-pressure boiling surface. Possibly because the enhanced surface was flattened from a round tube, ...
