Dr. Vlodek Tarnawski

Dr. Vlodek Tarnawski studies the thermal and transport properties of soils and how these properties change with mineral composition and moisture level. Reliable estimates of soil thermal conductivity are needed for heat and moisture flow analyses of in-ground engineering systems, facilities, and structures. For example, proper or efficient design of in-ground heat exchangers and heat-pumps, high voltage power cables, hot water or steam pipelines, chilled gas pipelines, and nuclear waste vaults may all require or benefit from thermal analyses, which require detailed knowledge of the local soil’s thermal properties. Analyses requiring thermal properties may also be of benefit when designing buildings, roads, airfields, or extraction processes for natural deposits, such as tar sands.
To date, Dr. Tarnawski has characterized the thermal properties of 40 distinct Canadian field soils, and defined how these properties vary with differing levels of moisture content. Full mineral analysis has enabled Dr. Tarnawski to relate changes in mineral composition to changes in thermal properties. In order to complete these studies, Dr. Tarnawski has designed, built, and characterized both laboratory-based thermal conductivity probes, and portable, smart conductivity probes. Using his extensive knowledge of the thermal properties of soils, Dr. Tarnawski has also conducted several studies of in-ground heat pump feasibility, efficiency, and optimization.
