Novel Approach for Heat Transfer Characterization in EOR Steam Injection Wells

Modeling of Heat Transfer in a Mist/Steam Impinging Jet

The addition of mist to a flow of steam or gas offers enhanced cooling for many applications, including cooling of gas turbine blades. The enhancement mechanisms include effects of mixing of mist with the gas phase and effects of evaporation of the droplets. An impinging mist flow is attractive for study because the impact velocity is relatively high and predictable. Water droplets, less than 1...

Mist/Steam Heat Transfer in Confined Slot Jet Impingement

Internal mist/steam blade cooling technology has been considered for the future generation of Advanced Turbine Systems (ATS). Fine water droplets of about 5 mm were carried by steam through a single slot jet onto a heated target surface in a confined channel. Experiments covered Reynolds numbers from 7500 to 25,000 and heat fluxes from 3 to 21 kW/m. The experimental results indicate that the co...

Hot steam transfer through heat protective clothing layers.

The aim of this study was to analyse the transfer of steam through different types of textile layers as a function of sample parameters such as thickness and permeability. In order to simulate the human body, a cylinder releasing defined amounts of moisture was also used. The influence of sweating on heat and mass transfer was assessed. The results show that in general impermeable materials off...

In-situ Delivery of Heat by Thermal Conduction and Steam Injection for Improved Dnapl Remediation

Thermal Conduction Heating (TCH) is a major component of In Situ Thermal Desorption (ISTD), a soil remediation technology in which heat and vacuum are applied simultaneously. Heat flows into the soil primarily by conduction from heaters typically operated between 1000 and 1500oF (540 and 815oC). The heaters are installed in wells at regular intervals within the soil. As the soil is heated, wate...
