Heat transfer has emerged as a central discipline in contemporary engineering science.
The research activity of a few decades ago—the material reviewed in the first
handbooks—has distilled itself into textbook concepts and results. Heat transfer has
become not only a self-standing discipline in the current literature and engineering
curricula, but also an indispensable discipline at the interface with other pivotal and
In smaller regions such as the Carpathian Basin (located in Eastern/Central Europe), 50 km
horizontal resolution may still not be appropriate to describe the meso-scale processes (e.g.,
cloud formation and convective precipitation). For this purpose on a national level several
RCMs have been adapted with finer resolution (25 and 10 km). Here, results from two of the
adapted RCMs for Hungary are analyzed, namely, models PRECIS and RegCM.
In this paper, first, data and models from PRUDENCE, PRECIS and RegCM are presented.

Heterogeneous nanofluids: natural convection heat transfer enhancement
Fakhreddine Segni Oueslati1, Rachid Bennacer2*
Abstract Convective heat transfer using different nanofluid types is investigated. The domain is differentially heated and nanofluids are treated as heterogeneous mixtures with weak solutal diffusivity and possible Soret separation.
To simulate the incompressible ﬂow in complex three-dimensional geometry eﬃciently and accurately, a solver based on solution of the Navier-Stokes equations in the generalized curvilinear coordinate system was developed. The system of equations in three-dimension are solved simultaneously by the artiﬁcial compressibility method. The convective terms are diﬀerenced using a ﬂux diﬀerence splitting approach. The viscous terms are diﬀerenced using second-order accurate central differences. An implicit line relaxation scheme is employed to solve the numerical system of equations.

When unfired units are designed with higher steam conditions for
combined cycle, multiple-pressure units are usually applied to
increase exhaust heat recovery and enhance system performanc
The intermediate level may be that required for steam injection fo
NOx control and/or a process level. In applications using natural
gas, a third pressure level will further enhance overall system
performance. Typical design practice is that unfired HRSGs are
convective heat exchangers that respond to the exhaust
conditions of the gas turbine.
Chapter 2 - Energy, energy transfer, and general energy analysis. The objectives of Chapter 2 are to: Introduce the concept of energy and define its various forms; discuss the nature of internal energy; define the concept of heat and the terminology associated with energy transfer by heat; discuss the three mechanisms of heat transfer: conduction, convection, and radiation; define the concept of work, including electrical work and several forms of mechanical work;...
