heat flow equation
31Differential equation — Not to be confused with Difference equation. Visualization of heat transfer in a pump casing, created by solving the heat equation. Heat is being generated internally in the casing and being cooled at the boundary, providing a steady state… …
32Plug flow reactor model — The plug flow reactor (PFR) model is used to describe chemical reactions in continuous, flowing systems. The PFR model is used to predict the behaviour of chemical reactors, so that key reactor variables, such as the dimensions of the reactor,… …
33Concentric tube heat exchanger — Concentric Tube (or Pipe) Heat Exchangers are used in a variety of industries for purposes such as material processing, food preparation and air conditioning.[1] They create a temperature driving force by passing fluid streams of different… …
34Eikonal equation — The eikonal equation is a non linear partial differential equation of the form: | abla u(x)|=F(x), xin Omega subject to u| {partial Omega}=0, where Omega is an open set in mathbb{R}^n with well behaved boundary, F(x) is a function with positive… …
35elliptic equation — ▪ mathematics any of a class of partial differential equations (partial differential equation) describing phenomena that do not change from moment to moment, as when a flow of heat or fluid takes place within a medium with no accumulations …
36Two-phase flow — In fluid mechanics, two phase flow occurs in a system containing gas and liquid with a meniscus separating the two phases. Historically, probably the most commonly studied cases of two phase flow are in large scale power systems. Coal and gas… …
37Multiphase flow — In fluid mechanics, multiphase flow is a generalisation of the modelling used in two phase flow to cases where the two phases are not chemically related (e.g. dusty gases) or where more than two phases are present (e.g. in modelling of… …
38Mason equation — The Mason equation is an approximate analytical expression for the growth (due to condensation) or evaporation of a water droplet it is due to the meteorologist B. J. Mason.[1] The expression is found by recognising that mass diffusion towards… …
39Mass flow sensor — A mass airflow sensor. A mass air flow sensor is used to find out the mass flowrate of air entering a fuel injected internal combustion engine. The air mass information is necessary for the engine control unit (ECU) to balance and deliver the… …
40Constant flux calorimetry — A key part of Reaction Calorimetry is the ability to control temperature in the face of extreme thermal events. Once the temperature is able to be controlled measurement of a variety of parameters can allow an understanding of how much heat is… …
