Eye movement in post-exercise effects A notable phenomenon in the field of visual science is the post-exercise effect (MAE), which is believed to provide a way to combine current neurophysiological knowledge with measurable visual phenomena. The MAE is described as a visual illusion arising from observing any number of motion types (ie, linear, spiral, radial or rotational in the lateral or vertical direction). Watch the moving object for a while until the eye adapts to the movement.
Convection heat transfer mode includes mechanism. In addition to energy transfer by specific molecular motion (diffusion) energy is transferred through large or macroscopic motion of the fluid. This movement is related to the fact that at any time many molecules move together or as agglomerates. This movement contributes to heat transfer in the presence of a temperature gradient. Total heat transfer is due to the superposition of energy transfer by random motion of the molecule and the overall motion of the fluid, since the molecules in the aggregate maintain their random motion. The term convection is often used when referring to such cumulative transport, whereas the term convection is used when referring to transport by large fluid transfer.
Convective heat transfer or convection is the transfer of heat from one location to another by fluid motion, which essentially conveys heat through mass transfer. Mass movement of fluid improves heat transfer in many physical situations, such as, for example, heat transfer between a solid surface and a fluid. Convection is usually the main form of liquid and gas heat transfer. It is sometimes discussed as a third method of heat transfer, but convection is commonly used to describe the combined effects of heat transfer (diffusion) in a fluid and heat transfer through a large amount of fluid flow. The transport process by fluid transport is called advection, but pure advection is usually related only to the transport of substances in fluids such as cobble transfer in rivers.
Convective heat transfer is one of the main types of heat transfer, convection is also the main mode of mass transfer of fluid. Both convective heat and mass transfer are via diffusion - random Brownian motion of individual particles in the fluid, where material and heat are transported through a larger flow in the fluid. In the context of heat and mass transfer, the term "convection" is used to refer to the combined effects of advection and diffusion migration. The term "convection" is used to mean "free heat convection" (natural thermal convection) due to differences in buoyancy due to temperature, not "forced convection" other than forces other than buoyancy (such as pumps) and fans . ) Move the liquid. However, in mechanics, it is a general meaning to use the word "convection" correctly, and for the sake of clarity, it is necessary to qualify various types of convection.
