Hoval has announced it has launched a modular, scalable solution for heating and ventilating warehouses and other 'shed' type buildings of any size and height, providing significantly improved control of thermal stratification compared to conventional systems.

In early August 2012, air temperatures declined and hypolimnion temperatures converged with those of the epilimnion, eliminating the thermal stratification that had inhibited mixing between the upper and lower zones of the lake (Fig.
Such recirculation results in thermal stratification in the chamber forming a zone of relatively cold air near the floor.

Thermal stratification on the left side of the cavity is observed and thermal boundary layers are becoming thinner than the Rayleigh increases.

* Energy use can be reduced through a variety of strategies including controlled thermal stratification, higher supply air temperatures, and reduced static pressures in under floor plenum.
Consider a steady, incompressible, laminar flow of an electrically conducting non-Newtonian (Casson) fluid over a melting surface on upper horizontal paraboloid of revolution in the presence of viscous dissipation and thermal stratification. The x-axis is taken in the direction of motion and y-axis is normal to the flow as shown in Figures 1(a) and 1(b).
The entrainment of such jet causes the cold air outside and the cooler air in the depth of the tunnel to flow along the bottom of the tunnel towards the explosion source in a natural convection process with thermal stratification. As time elapses, the high-temperature region gradually concentrates on the top and moves deep into the tunnel.
Shapiro and Fedorovish [15] presented analytical solution of one-dimensional laminar natural convection along an infinite vertical plate by introducing the pressure work term and the ambient thermal stratification in the thermodynamic energy equation for the case of unit Prandtl number.
Thermal stratification in the Sarajevo Valley was previously investigated by means of computer simulation and turbulence modelling [2].
