This article mainly makes a brief introduction about Microencapsulated Phase Change Material Slurries(MEPCMS) and its preparations ，the research status and several correlations of heat transfer in turbulent flow of MEPCMS are also listed.The influencing factors of turbulent heat transfer are mainly the degree of turbulence, the mass fraction and wall heating rate,particle size effects weakly.
Introduction Energy is the motive force of social development and the foundation of human survival.With the development of science and technology and the increasingly prominent energy and environment problems, the problems of heat transfer,heat and cold storage have emerged in the fields of power, metallurgy, chemical engineering and technology.Since the limited heat transfer ability of ordinary fluid can not meet the actual needs, in this case, the functional fluids with higher heat transfer capability are needed[1，2].
Microencapsulated Phase Change Material(MEPCM) is the new material which is fabricated by the PCM(Phase Change Material) as core material and polymer as wall material[3，4].The diameter varies from 1μm to 1000μm.

Introduction The field of composite materials has progressed greatly over the last several decades, and the widespread use of composite materials can be found in the fields where lightweight is a major concern for the design of engineering structures [1].
These “components” may act as the part(s) in the composite materials or structures for either functional or mechanical purposes.
Thus the application of organic polymeric materials is greatly expanded in engineering.

Traditional materials are mainly written materials.
But now, there are various materials, including video clips, films, graphs, tables and flashes to show the process of a certain subject.
There are more real life materials besides some pure literature.
Until now, nearly all college teachers are using and benefiting from a diversified scope of materials.

Putting fly ash into polymer to make composite materials can improve weather durability, electrical properties, fire resistance of polymer as well as reduce the cost of products when applied in a number of technical fields.
Therefore, in this work, some characteristics and properties of composite materials based on 2 polymers (EVA and LDPE) with non-modified and modified fly ash composites with vinyltrimetoxy silane (VTMS) has been studied.
Experimental Details Materials and chemicals - Fly ash (FA) of Pha Lai thermoelectric plant has content of SiO2 + Fe2O3 + Al2O3 ≥ 86 %, 0.3 % moisture content, particle size primarily in the range of 1-5 μm
