Overview

What is he best known for?

The fields of study he is best known for:

  • Thermodynamics
  • Mechanical engineering
  • Electrical engineering

His primary areas of study are Thermodynamics, Refrigeration, Heat transfer, Heat transfer coefficient and Transcritical cycle. His study focuses on the intersection of Thermodynamics and fields such as Mechanics with connections in the field of Injector. His biological study spans a wide range of topics, including Pressure drop and Refrigerant.

He focuses mostly in the field of Heat transfer, narrowing it down to topics relating to Evaporator and, in certain cases, Condenser and Coefficient of performance. While the research belongs to areas of Heat transfer coefficient, Eckhard A. Groll spends his time largely on the problem of Turbulence, intersecting his research to questions surrounding Tube, Electromagnetic coil, Fin and Composite material. Eckhard A. Groll has included themes like Crank and Piston in his Transcritical cycle study.

His most cited work include:

  • A composite heat transfer correlation for saturated flow boiling in small channels (255 citations)
  • Transcritical CO2 refrigeration cycle with ejector-expansion device (244 citations)
  • Efficiencies of transcritical CO2 cycles with and without an expansion turbine (199 citations)

What are the main themes of his work throughout his whole career to date?

Eckhard A. Groll mainly focuses on Gas compressor, Mechanical engineering, Thermodynamics, Refrigerant and Mechanics. Within one scientific family, Eckhard A. Groll focuses on topics pertaining to Scroll under Gas compressor, and may sometimes address concerns connected to Waste heat recovery unit. Eckhard A. Groll combines subjects such as Flow control, Control theory, Refrigeration, Evaporator and Air conditioning with his study of Refrigerant.

His research integrates issues of Transcritical cycle, Injector and Process engineering in his study of Air conditioning. His study in Mechanics is interdisciplinary in nature, drawing from both Heat exchanger and Suction. His research in Heat transfer intersects with topics in Microchannel and Pressure drop.

  • Gas compressor (32.74%)
  • Mechanical engineering (28.32%)
  • Thermodynamics (21.68%)

What were the highlights of his more recent work (between 2015-2021)?

  • Gas compressor (32.74%)
  • Mechanical engineering (28.32%)
  • Vapor-compression refrigeration (10.18%)

In recent papers he was focusing on the following fields of study:

Eckhard A. Groll mostly deals with Gas compressor, Mechanical engineering, Vapor-compression refrigeration, Waste heat recovery unit and Heat pump. His Gas compressor research is included under the broader classification of Thermodynamics. Eckhard A. Groll specializes in Thermodynamics, namely Coefficient of performance.

His Mechanical engineering research includes elements of Surface-area-to-volume ratio and Leakage. His Vapor-compression refrigeration research is multidisciplinary, incorporating elements of Nuclear engineering, Injector, Refrigeration and Transcritical cycle. His Refrigerant research incorporates elements of Evaporator and Air conditioning.

Between 2015 and 2021, his most popular works were:

  • Comprehensive experimental performance analyses of an ejector expansion transcritical CO2 system (44 citations)
  • Experimental and numerical analyses of a 5 kWe oil-free open-drive scroll expander for small-scale organic Rankine cycle (ORC) applications (29 citations)
  • Development and a Validation of a Charge Sensitive Organic Rankine Cycle (ORC) Simulation Tool (21 citations)

In his most recent research, the most cited papers focused on:

  • Mechanical engineering
  • Thermodynamics
  • Electrical engineering

Gas compressor, Mechanical engineering, Organic Rankine cycle, Waste heat recovery unit and Thermodynamics are his primary areas of study. His studies deal with areas such as Heat transfer and Leakage flow, Leakage as well as Gas compressor. As a part of the same scientific study, he usually deals with the Mechanical engineering, concentrating on Isentropic process and frequently concerns with Scroll compressor.

His Waste heat recovery unit study incorporates themes from Surface-area-to-volume ratio, Degree Rankine and Scroll. His Thermodynamics study frequently draws connections to other fields, such as Mechanics. He usually deals with Refrigerant and limits it to topics linked to Evaporator and Psychrometrics, Superheating, Cooling capacity, Electronic circuit and Air conditioning.
