isoflux

English

Etymology

From iso- +‎ flux.

Noun

isoflux (plural isofluxes)

1. (physics) The product obtained by multiplying the flux measurement by the isotopic signature.
   • 2001, Ernst-Detlef Schulze, Martin Heimann, Sandy Harrison, Global Biogeochemical Cycles in the Climate System, →ISBN, page 288:

     It is even more difficult when one considers that the disequilibrium is spatially variable so that the global isoflux must be properly flux-weighted for the effect of different regions.

   • 2006, Heinrich D. Holland, Ralph F. Keeling, Karl K. Turekian, The Atmosphere, →ISBN, page 205:

     As the leaf isoflux slowly diminishes, the respiration isoflux, that has lagged photosynthesis due to the slow increase in soil temperature, takes over bringing about a seasonal minimum in late summer/early fall.

   • 2009, Asko Noormets, Phenology of Ecosystem Processes, →ISBN:

     Trends in F_N were mimicked by that of the isoflux, but in the opposite direction, since isoflux is a product of a negative flux and a negative isotopic signature (Fig. 5).

Adjective

isoflux (not comparable)

1. Pertaining to a uniform level of flux.
   • 2008, Juan Guillermo Araya, DNS of Turbulent Wall Bounded Flows with a Passive Scalar, →ISBN, page 13:

     The rms of thermal fluctuations at the wall were zero for the isothermal condition and nonzero for the isoflux condition.

   • 2010, Rainer Sandau, Hans-Peter Roeser, Arnoldo Valenzuela, Small Satellite Missions for Earth Observation, →ISBN, page 363:

     An isoflux antenna can be used to counteract the change of free-space loss throughout an orbital pass to maintain a constant link margin.

   • 2015, Myer Kutz, Mechanical Engineers' Handbook, Volume 4: Energy and Power, →ISBN:

     Asymmetry can also occur if adjacent channel walls are isothermal but at different temperatures or isoflux but dissipating different heat fluxes.
