Plenty of studies exist in books and archival journals dealing with different types of heat exchangers. In the paper an analytical approach to evaluate the overall heat transfer coefficient of a new type heat exchanger is presented. Derived equations

This paper deals with the numerical modelling of heavy residual fuel oil combustion. Some results of combustion-generated nitric oxide and coke are presented. The emissions of both species are greatly affected by a gas temperature and thus the modell

The design of pumps has been mainly based on results obtained from experiments. Because there has been no detailed information concerning very complicated flow fields inside pumps, only by accident have some new ideas been found. At present, numerica

Hydraulic characteristics of different sewer shapes are studied. The sewer must carry a very large flow rate for example in storm conditions, but most of the time there is very little flow at the bottom. This causes sedimentation of particles, which

An analysis of natural convection from a vertical plate fin when the fin base temperature is below the dew point of the surrounding air is presented in this paper. The analytical solution derived is based upon a constant heat and mass transfer coeffi

The minimum thermal resistance for isothermal plate fin arrays with array volume, number of the fins and either fan power or pressure drop fixed can be found in the literature. We solve the same fundamental problems for non-isothermal fin arrays by u

The presence of particles in the fluid flow modulates strongly the conveying phase turbulence, even with very small particle loadings. This work is concerned with the upward, fully developed pipe flow of a gas-particle suspension in which the dispers
