Smoke Control in Special Structure
Building codes of almost all countries generally have a ‘size limitation of building and compartment’ which states a maximum floor area and cubical content for various uses and configuration. If the maximum compartment size is exceeded, there is usually provision for relaxation of the codes which will involve at least some of the following: a) occupancy levels, b) means of escape, c) sprinkler ...
متن کاملMid-level smoke control for 2D animation
In this paper we introduce the notion that artists should be able to control fluid simulations by providing examples of expected local fluid behavior (for instance, an artist might specify that magical smoke often forms star shapes). As our idea fits between high-level, global pose control and low-level parameter adjustment, we deem it mid-level control. We make our notion concrete by demonstra...
متن کاملEvaluating the Smoke Hazard from Fires in Large Spaces
Current codes in many countries require that the smoke layer be maintained a particular distance above the highest walking surface in an atrium. The smoke exhaust capacity to accomplish the required performance can be extraordinary, especially in a tall atrium with the upper floors open to the atrium. The effect of exposure to smoke is a function of the magnitude of the smoke signature, e.g. co...
متن کاملCigarette smoke in closed spaces.
For years it has been postulated that the cigarette smoker adversely affects the nonsmoker by contaminating the indoor atmosphere (2,3). Recently, the U.S. Surgeon General, J. L. Steinfeld, focused public attention on the question when he requested a ban on smoking in closed public spaces (4). The average person spends the great majority of his time, probably 80 to 90 percent, indoors (5);thus,...
متن کاملTarget particle control of smoke simulation
User control over fluid simulations is a long-standing research problem in computer graphics. Applications in games and films often require recognizable creatures or objects formed from smoke, water, or flame. This paper describes a two-layer approach to the problem, in which a bulk velocity drives a particle system towards a target distribution, while simultaneously a vortex particle simulatio...
