Turbulent flows in a spiral double-pipe heat exchanger
International journal of numerical methods for heat & fluid flow, 2019Purpose This paper aims to study the fluid flow and heat transfer through a spiral double-pipe heat exchanger. Nowadays using spiral double-pipe heat exchangers has become popular in different industrial segments due to its complex and spiral structure,

This chapter provides a review of the methods used in the thermal analysis of heat exchangers. Equipment used in double-pipe (hairpin), shell-and-tube, and plate heat exchangers is described. The overall heat-transfer coefficient, fouling factors, LMTD (logarithmic mean temperature difference) correction factor, and heat-exchanger effectiveness are ...

Fluoropolymer heat exchangers are the only polymeric heat exchangers to offer thetemperature capabilities and corrosion resistance necessary to heat and cool acid- and caustic-based plating baths. They offer economical solutions to the problems of maintaining precise temperature control of baths for optimum product quality.

HEAT EXCHANGER FOR IN-GROUND HEAT STORAGE
Chemical Engineering Communications, 1980The first phase of a research project using undisturbed soil for sensible heat storage is described. A laboratory scale model of a heat exchange system was constructed and tested. Thermal charging and recovery rates, modes of heat transport and transient temperature conditions, as well as over-all heat storage performance of the unit are given.

AbstractStudies of the effects of nasal respiration on the lower respiratory tract, and on metabolic processes generally, have largely been confined to those occurring during inspiration. Expiration through the nose has equally profound effects and has been studied in detail in some animals.Under certain circumstances both heat and water loss from the ...

Matériaux & Techniques, 1992
Plastic properties may be used in the manufacturing of heat exchangers. Considering their advantages, their field of application is quite large: low temperature heat recovery, concentration of solutions. Three equipment are described: a liquid-liquid shell and tube exchanger, a gas-gas shell exchanger and a falling flow evaporator.

Dynamic models for heat exchangers and heat exchanger networks
Computers & Chemical Engineering, 1994Abstract Dynamic models are needed to assess controllability of heat exchangers and heat exchanger networks. A simple model is desirable, but all important model features must be included. We discriminate between important and less important model features by order of magnitude argumentation, comparison of controllability measures and dynamic ...
