  2. Value engineering - Wikipedia

    en.wikipedia.org/wiki/Value_engineering

    Value engineering can lead to the substitution of lower-cost materials, as with the exterior cladding that accelerated the Grenfell Tower fire in London. [1] [2]Value engineering (VE) is a systematic analysis of the functions of various components and materials to lower the cost of goods, products and services with a tolerable loss of performance or functionality.

  3. Phase-change material - Wikipedia

    en.wikipedia.org/wiki/Phase-change_material

    A phase-change material (PCM) is a substance which releases/absorbs sufficient energy at phase transition to provide useful heat or cooling. Generally the transition will be from one of the first two fundamental states of matter - solid and liquid - to the other.

  4. Computational Fluid Dynamics for Phase Change Materials

    en.wikipedia.org/wiki/Computational_Fluid...

    Computational Fluid Dynamics (CFD) modeling and simulation for phase change materials (PCMs) is a technique used to analyze the performance and behavior of PCMs. The CFD models have been successful in studying and analyzing the air quality, natural ventilation and stratified ventilation, air flow initiated by buoyancy forces and temperature space for the systems integrated with PCMs.

  5. Phase transition - Wikipedia

    en.wikipedia.org/wiki/Phase_transition

    In physics, chemistry, and other related fields like biology, a phase transition (or phase change) is the physical process of transition between one state of a medium and another. Commonly the term is used to refer to changes among the basic states of matter : solid , liquid , and gas , and in rare cases, plasma .

  6. Transport phenomena - Wikipedia

    en.wikipedia.org/wiki/Transport_phenomena

    Transport phenomena are ubiquitous throughout the engineering disciplines. Some of the most common examples of transport analysis in engineering are seen in the fields of process, chemical, biological, [ 1 ] and mechanical engineering, but the subject is a fundamental component of the curriculum in all disciplines involved in any way with fluid ...

  7. Value-based engineering - Wikipedia

    en.wikipedia.org/wiki/Value-based_Engineering

    In VBE, ethical system design is achieved through four processes aligned with ISO/IEC 15288.. Concept of operation and context exploration process: This process aims to gain an initial understanding of the context, relevant stakeholders, legal, social, environmental, and ethical feasibility, and control over the intended external partners of a proposed system, and to develop a tangible concept ...

  8. Solid solution - Wikipedia

    en.wikipedia.org/wiki/Solid_solution

    The IUPAC definition of a solid solution is a "solid in which components are compatible and form a unique phase". [3]The definition "crystal containing a second constituent which fits into and is distributed in the lattice of the host crystal" given in refs., [4] [5] is not general and, thus, is not recommended.

  9. Phase diagram - Wikipedia

    en.wikipedia.org/wiki/Phase_diagram

    A phase diagram in physical chemistry, engineering, mineralogy, and materials science is a type of chart used to show conditions (pressure, temperature, etc.) at which thermodynamically distinct phases (such as solid, liquid or gaseous states) occur and coexist at equilibrium.
