BIONIC PRINCIPLES OF OPTIMIZATION OF HEAT AND COLD CONDUITS

Abstract

Bionic approach to create technological devices based on the fact that a number of ideas and the basic elements of the device borrowed from living nature. In this case, it is postulated that over millions of years of evolution in living nature have already been found optimal solutions, which require only a correct interpretation. As a prototype of heat or cold conduits in living nature, taking into account the analogy between heat and mass transfer, select the root system of plants. In morphology root system of plants is divided into two types: fibrous root system type and taproot system. In accordance with these two types of heat reviewed: branched and unbranched. An algorithm for optimizing the shape and size of heating conduits. Received an analytical expression allowing to evaluate the warm-up time unbranched heat conductor and the maximum temperature that can be achieved in electric heating heat conductor. On the example of the longitudinal tube riffles forming atmospheric evaporators high pressure branched were optimized of heating conduits. The choice of the optimal form of ribs for chess and in-line tube bank. For staggered multiple rows of tubes is the best ribs in the form of snowflakes. For in-line tube bank proved optimal ribs with four diagonal ribs.
