1. Effective Models for Simulation of Thermal Stratification and Mixing Induced by Steam Injection into a Large Pool of Water
Sammanfattning : Steam venting and condensation in a large pool of water creates both a source of heat and a source of momentum. Complex interplay between these two sources leads to either thermal stratification or mixing. LÄS MER
2. Steam condensation in a water pool and its effect on thermal stratification and mixing
Sammanfattning : The Pressure Suppression Pool (PSP) of a Boiling Water Reactor (BWR) is a large heat sink designed to limit the containment pressure by condensing steam released from the primary coolant system. The development of thermal stratification is a safety concern since it leads to higher containment pressures than in completely mixed conditions, and can affect the performance of systems such as the emergency core cooling and containment spray, which the use PSP as a source of water.

3. Short term water heat storage : an experimental investigation of thermal stratification
Sammanfattning : .... LÄS MER
4. From alpha to beta ocean: Exploring the role of surface buoyancy fluxes and seawater thermal expansion in setting the upper ocean stratification
Sammanfattning : The ocean plays a central role in the climate system by absorbing excess anthropogenic heat and carbon dioxide. Moreover, the ocean circulation distributes heat from the tropics towards the poles. Due to the large ocean stratification, vertical exchanges between the ocean interior and the surface are limited.

5. Phytoplankton and Physical Disturbance : Seasonal dynamics in temperate Lake Erken, Sweden
Sammanfattning : Phytoplankton mirrors changes in the environment and plays an important role in biogeochemical processes. Phytoplankton dynamics is the outcome of both autogenic succession and external disturbances. LÄS MER
