A study of the influence of free convection on coagulation process
, 1999 It was assumed [1, 2] that gravity affects the coagulation process in two ways: free convection, which is hard to be avoided on the ground and sedimentation, which can be greatly reduced by the density-matching method.

Effects of convection and solid wall on the diffusion in microscale convection flows
, 2010 The diffusive transport properties in microscale convection flows are studied by using the direct simulation Monte Carlo method. The effective diffusion coefficient D is computed from the mean square displacements of simulated molecules based on the ...

Advanced Science, EarlyView.A CCM‐based architectural strategy is introduced for high‐temperature PEM fuel cells, enabling MPL‐free carbon paper gas diffusion layers via decal‐transfer processing. By co‐engineering the CCM, GDL, and a G‐foam flow field, oxygen transport is enhanced while phosphoric‐acid leakage is suppressed, resulting in high power density and stable operation ...

Unsteady free convection flow over a three- dimensional stagnation point with internal heat generation or absorption [PDF]
, 2011 This paper considers the effect of heat generation proportional to(T-T8)p, where T is the local temperature and T8 is the ambient temperature, in unsteady free convection flow near the stagnation point region of a three-dimensional body.

Convection forced by a descending dry layer and low-level moist convergence
, 2009 This is the post-print version of the Article - Copyright @ 2009 Wiley-BlackwellA narrow line of convective showers was observed over southern England on 18 July 2005 during the Convective Storm Initiation Project (CSIP). The showers formed behind a cold

Advanced Science, EarlyView.Herein, we propose a solar‐powered heavy metal trap (SPHT) for sludge disposal. The indoor experiments demonstrated that the sludge water content decreased from 90 % to 31 %, coupled with a decrease in heavy metal content to 6 % at most. Furthermore, the designed SPHT generated an initial potential of 0.10 V, and monitoring this hydrovoltaic potential ...

Passive solar energy : modifications of existing masonry walls to improve thermal performance. [PDF]
, 1986 Existing brick walls usually have a high U value, one method of improvement is by insulation, but if the wall faces approximately south, it is possible that greater benefits could be obtained by improving the wall's performance as a solar collector ...
