Experimental and Analytical Investigation of the Transient Thermal Response of Air Cooled Data Centers
<p>This work investigates the transient response of the thermal environment in air cooled data centers through experiments, analytical and computational tools. The key thermal characteristics of the various data center components were extracted from a set of experiments. This includes the …

Thermal Characterization of Graphitic Carbon Foams for Use in Thermal Storage Applications
… foams are currently being studied for use as thermal conductivity enhancers (TCEs) in thermal energy storage (TES) systems. TES systems store energy using the latent heat capacity of phase change materials (PCMs). Due to the low thermal conductivity of most PCMs, TCEs are necessary to evenly …

Design and Simulation of Passive Thermal Management System for Lithium-Ion Battery Packs on an Unmanned Ground Vehicle
<p>The transient thermal response of a 15-cell, 48 volt, lithium-ion battery pack for an unmanned ground vehicle was simulated with ANSYS Fluent. Heat generation rates and specific heat capacity of a single cell were experimentally measured and used as input to the thermal model. A heat generation …

A transient heat probe sensor for measuring transpiration in the stem of woody plants.
… is able to work as flowmeter since its transient thermal response was affected by the local fluid flow. The natural logarithm of the fractional response of the thermistor probe indicated that the system can not be analysed as a first order model. Non-linear regression analysis showed …

Viability assessment of enhancing dry cooling systems using thermal storage ponds
… system requires an accurate model to predict the transient thermal response of the pond. No such pond model is available in open literature due to the pond under consideration having a unique size as well as size to depth ratio. Various heat transfer modes are numerically modelled for large …
