The phrase "ash accumulation" is correct and usable in written English.
It can be used in contexts related to environmental science, geology, or any discussion involving the buildup of ash, such as from volcanic eruptions or combustion processes.
Example: "The ash accumulation from the recent volcanic eruption has significantly impacted air quality in the surrounding areas."
Alternatives: "ash buildup" or "ash deposit".
It is found that ash accumulation is strongly influenced by the flue gas temperature in comparison with the Engineering Acid Dew Temperature (EADT).
In ITER, one of the key issues to achieve 400 s driven-burn operation at Q about 10 (Technical Basis for the ITER-FEAT Outline Design—Sectisn I-3.2.2.IAEA) is helium ash accumulation.
Fig. 4 (Top) Dispersed (blue line) vs. discrete (red field) ash accumulation in the Caribbean Sea.
These curves represent another way of displaying the same results as in Figs. 4 and 6 (total ash accumulation from a Santorini Weak typical case).
As a consequence, credible volcanic ash accumulation beyond the 500 km limit may not have been captured, and this had important implications for the Asia-Pacific assessment.
Fig. 6 Probability maps that represent total ash accumulation on the ground over a most likely eruption scenario as computed by the TEPHRA2 model.
Phases B and A are made up of light colored sandy silts and ash accumulations.
Plotting the total ash accumulations over two years therefore provides an estimate of the maximum loading; erosion, wind re-distribution, rain and clean-up operations will act to reduce this load in uncertain ways.
Ash accumulations will decrease traction, especially when wet, and cover road markings.
This practice was observed to make use of 1) the shadow of the trunk which protects the germ against the heat of the sun; 2) ash accumulations along the trunk; 3) protection against itching parts of the maize plants when walking through the field.
Therefore, the flue gas temperature can be controlled to enhance particle accumulation and improve ash collection efficiency.
