- Convection
- Currents created by heating air, which then rises and pulls cooler air behind it. also see radiation.
- The transfer of energy through a liquid or gas due to the motion of the medium.
- Конвекция
- Heat transmission, either natural or forced (by means of a fan), by currents of air control joint control-joint grouting the injection of grout into a control joint.
- The rising of heated surface air.
- Конвекция. установившееся внутреннее движе-. нне в каком-либо слое или воздухе, приводящее к вертикальному переносу теплоты, массы и т. д. (вмо). в воздухе конвекция чаще всего обусловлена плавучестью воздушных масс, контактирующих с нагретой поверхностью, что приводит к возникновению вертикального потока воздуха над поверхностью. конвекция может возникать также в результате воздушных течений и завихрений при встрече с механическими препятствиями, как, например, при прохождении воздуха над возвышенностью.

- The transfer of heat energy through gasses and liquids by the amount and mixing of those fluids.

Convection, английский
Convection, французский
Fluid circulation driven by large temperature gradients; the transfer of heat by this automatic circulation.
Convection, английский
Describes the vertical air motion that occur when the atmosphere is unstable. convection often gives rise to the formation of convective cloud (cumulus, towering cumulus and thunderclouds) and showery precipitation.
Convection, английский
In physics, convection is the transport and mixing of properties (energy, heat, moisture, etc.) of a fluid by mass motion of that fluid. in meteorology, convection generally refers to such transport and mixing in the vertical direction, and advection refers to processes in the horizontal plane.
Convection circulation, английский
In a hot-water heating system, the movement of water through the pipes as a result of gravity which causes the lighter, warm water in the system to rise, and the cool water to fall.
Convection current, английский
The transfer of heat that results from the movement of air from one location to another, usually as a result of a stream of air produced by thermal convection caused by differences in temperature.
Convection flows error, английский
Погрешность от конвективных течений
Convection heating, английский
Heating which results from the movement of air (or any other gas or liquid), carrying heat from the hotter to the cooler spaces.
Convection loss, английский
Heat loss in a building resulting from temperature differences in the heated space.
Convection thermique, французский
Convection [geothermal], английский
Heat transfer by the physical movement of molecules (i.e., fluid). the word is used in two contexts

Convective clouds, английский
Clouds formed atop rising air columns. cumulus clouds are convective clouds.

Конвективное погасание частиц топлива
Convective heat transfer coefficient, английский
Convective heat transfer coefficient:, английский
Convective heat flux to the member related to the difference between the bulk temperature of gas bordering the relevant surface of the member and the temperature of that surface
Convective movement, английский

Convector, английский
A surface designed to transfer its heat to a surrounding fluid largely or wholly by convection; units for water or steam heating usually are installed against the wall or in a recess in the wall. conveyance 257

Temperature, английский
- Température
- Dry-bulb - temperature of air as indicated by a standard thermometer.
- An expression of thermal energy density. how hot or cold an object is.
- The measure of the intensity of heat that a substance possesses.
- Температура
- Температура тмр test methods and procedures методы проведения испытаний и последовательность их проведения тмр theodolite measuring point кинотеодолитная станция
- Temperatura, fiebre
- The condition attained when the wetted wick of a wet-bulb thermometer has reached a stable and constant temperature when exposed to moving air in excess of 900 ft (274.3 m) per minute.
- 1. the heat of the body or of the surrounding air, measured in degrees the doctor asked the nurse what the patient’s temperature was. his temperature was slightly above normal. the thermometer showed a temperature of 99°f. to take a patient’s temperature to insert a thermometer in someone’s body to see what his or her body temperature is they took his temperature every four hours. when her temperature was taken this morning, it was normal. 2. illness when your body is hotter than normal he’s in bed with a temperature. her mother says she’s got a temperature, and can’t come to work. comment: the average body temperature is about 37° celsius or 98° fahrenheit. this temperature may vary during the day, and can rise if a person has taken a hot bath or had a hot drink. if the environmental temperature is high, the body has to sweat to reduce the heat gained from the air around it. if the outside temperature is low, the body shivers, because rapid movement of the muscles generates heat. a fever will cause the body temperature to rise sharply, to 40°c (103°f) or more. hypothermia exists when the body temperature falls below about 35°c (95°f).
- Повышение температуры бетона ~ of truss высота фермы jet ~ высота подъёма горизонтальной неизотермической приточной струи, «всплывающей» над приточным отверстием

- Normal adult temperature varies among horses, but will usually range in degrees from 99.5°f to 100.5°f.
- A measure of the average kinetic energy of a material. the standard unit of temperature is a kelvin, (k). temperature determines the direction of heat flow between any two systems in thermal contact. heat will always flow from the area of higher temperature (t source) to one of lower temperature (t sink). temperature gradient (?t)
- A measure of the degree of molecular motion of a material compared to a reference point. temperature is measured in degrees farenheit (melting point of ice = 32 º f, boiling point of water = 212 º f) or degrees celsius (melting point of ice = 0 º c, boiling point of water = 100 º c).
- The degree of sensible heat of a body as measured by a thermometer or similar instrument.
- Measure of the intensity of particle motion in degrees celsius (°c) or degrees fahrenheit (°f) or, in the absolute scale, kelvin (k), where the increment of 1 k = 1 °c = 1.8 °f.
- Temperature of surrounding atmosphere. also called dry bulb temperature. compare standard atmospheric conditions. ampere (a): si unit of electric current. ampere per meter (a·m–1): si derived unit of magnetic field intensity. the measurement 1 a·m–1, for example, describes a current of 1 a flowing through a coil that is 1 m in diameter. compare oersted. ampere turn (at): in magnetic particle testing, unit for expressing the magnetomotive force required for magnetization using a coil in terms of the product of the number of coil turns and the current in amperes flowing through the coil. amplitude, echo: in ultrasonic testing, the vertical height of a received signal on an a-scan, measured from base to peak for a video presentation or from peak to peak for a radio frequency presentation.
- Measure of the intensity of particle motion in degrees celsius (°c), degrees fahrenheit (°f) or, in the absolute scale, kelvin (k) or degrees rankine (°r). an increment of 1 k = 1 °c = 1.8 °r = 1.8 °f. compare heat.
