A foil is an architectural device based on a symmetrical rendering of leaf shapes, defined by overlapping circles of the same diameter that produce a series of cusps to make a lobe. Typically, the number of cusps can be three ( trefoil ), four ( quatrefoil ), five (cinquefoil [ 1 ] ), or a larger number (multifoil). [ 2 ]
The dolphin flipper at bottom left obeys the same principles in a different fluid medium; it is an example of a hydrofoil. Streamlines on an airfoil visualised with a smoke wind tunnel An airfoil ( American English ) or aerofoil ( British English ) is a streamlined body that is capable of generating significantly more lift than drag .

ARCADIA, a model-based engineering method for systems, hardware and software architectural design. ARCADIA (Architecture Analysis & Design Integrated Approach) is a system and software architecture engineering method based on architecture-centric and model-driven engineering activities.
The engineering design process, also known as the engineering method, is a common series of steps that engineers use in creating functional products and processes. The process is highly iterative – parts of the process often need to be repeated many times before another can be entered – though the part(s) that get iterated and the number of such cycles in any given project may vary.
A foil generates lift primarily because of its shape and angle of attack. When oriented at a suitable angle, the foil deflects the oncoming fluid, resulting in a force on the foil in the direction opposite to the deflection. This force can be resolved into two components: lift and drag. This "turning" of the fluid in the vicinity of the foil ...
A less prescriptive approach to designing a basic design process for oneself has been outlined by J. Christopher Jones. [27] In the engineering design process systematic models tend to be linear, in sequential steps, but acknowledging the necessity of iteration. In architectural design, process models tend to be cyclical and spiral, with ...
In chemical engineering, process design is the choice and sequencing of units for desired physical and/or chemical transformation of materials. Process design is central to chemical engineering, and it can be considered to be the summit of that field, bringing together all of the field's components.
Design theory is a subfield of design research concerned with various theoretical approaches towards understanding and delineating design principles, design knowledge, and design practice. History [ edit ]
