摘要

本文给出了热球在粘性连续介质中运动时的阻力计算问题的详细解决方法。在固定情况下，当身体与环境的热交换不会导致其温度发生显着变化时，该问题在时间间隔上得到解决。考虑了极限情况，即当努塞尔数较大（导热系数较小）且被加热球的温度与环境温度一致时。

On the Drag Force of a Hot Ball

The paper provides a detailed solution to the problem of calculating the drag force of a hot ball moving in a viscous continuum. The problem is solved in the stationary case on time intervals when the heat exchange of the body with the environment does not lead to significant changes in its temperature. The limiting case is considered, when the Nusselt number is large (the thermal conductivity is small) and the temperature of the heated ball is considered constant together with the ambient temperature.

期刊介绍： Technical Physics is a journal that contains practical information on all aspects of applied physics, especially instrumentation and measurement techniques. Particular emphasis is put on plasma physics and related fields such as studies of charged particles in electromagnetic fields, synchrotron radiation, electron and ion beams, gas lasers and discharges. Other journal topics are the properties of condensed matter, including semiconductors, superconductors, gases, liquids, and different materials.
