When some are not adiabatic, then the system is not adiabatically enclosed, though adiabatic transfer of energy as work can occur across the adiabatic walls. The adiabatic enclosure is important because, according to one widely cited author, Herbert Callen , "An essential prerequisite for the measurability of energy is the existence of walls ...
An adiabatic process (adiabatic from Ancient Greek ἀδιάβατος (adiábatos) ' impassable ') is a type of thermodynamic process that occurs without transferring heat between the thermodynamic system and its environment. Unlike an isothermal process, an adiabatic process transfers energy to the surroundings only as work and/or mass flow.
Showing wall boundary condition. The most common boundary that comes upon in confined fluid flow problems is the wall of the conduit. The appropriate requirement is called the no-slip boundary condition, wherein the normal component of velocity is fixed at zero, and the tangential component is set equal to the velocity of the wall.

From a distance, massing, more than any architectural detail, is what creates the most impact on the eye. [6] Architectural details or ornaments may serve to reinforce or minimize massing. [7] Because it has a direct relation to the visual impact a building makes, massing is one of the most important architectural design considerations. [1]
Basic principle of the corbeled arch design ("false arch"). For the sake of comparison, a semicircular arch with wedge-shaped voussoirs maintained by a central keystone (" true arch"). A corbel arch (or corbeled / corbelled arch ) is an arch -like construction method that uses the architectural technique of corbeling to span a space or void in ...
In thermodynamics, a diathermal wall between two thermodynamic systems allows heat transfer but does not allow transfer of matter across it.. The diathermal wall is important because, in thermodynamics, it is customary to assume a priori, for a closed system, the physical existence of transfer of energy across a wall that is impermeable to matter but is not adiabatic, transfer which is called ...
For example, in the case in which two buildings at a location exist side by side with a gap, when a volume of wind blows around the ends of the buildings and through the gap, the sum of flow around each building and then its velocity increases as it travels through the gap, at the expense of pressure loss. As a result, there is a build up of ...
Unlike the physical objects manifesting the mass (for example, the floor, walls, and ceiling), the human experience of the void, air-filled indoor space is not obvious, [2] yet the idea of architectural space is very old, going back at least to the Ancient Greek: τάξις (táxis, "order"), a subdivision of a building into parts.
