Data confidence 70 medium

How this score is calculated

It is built from checkable properties of the record itself: whether the article has a DOI, how many independent sources confirmed its data, whether the required fields are filled in, and how recent the latest confirmation is. Disagreement between sources and a missing identifier lower it. A value of 80 or above means the record was published without further checking; 60 to 79 means it is published at reduced confidence, with a manual check advisable. A record verified by an editor by hand is never pushed below 90 by a recalculation. This scores our data about the article, not the article itself.

Abstract

Abstract This work is devoted to the methodology for conducting experiments to study the process of cooling by a low-pressure gas–droplet flow under conditions of high energy loads on the receiving surface of a lithium divertor module (LDM) layout. The paper describes in detail the design of the LDM model, all the main systems, parameters, and layout of the test bench. The operating modes of water and gas cooling systems have been calculated under thermal action on the LDM layout with a power equal to 5 MW/m2. A description of the experiment on the development of a technique for cooling an LDM layout with a low-pressure gas–droplet flow has been given.
