TL;DR: In this paper, the velocity distribution in steady state, hydrodynamically fully developed, laminar flow for Newtonian fluids in rectangular ducts is derived by using the finite Fourier transform.

TL;DR: In this article, the velocity and temperature distribution in steady state, hydro dynamically and thermally fully developed, laminar forced flow for Newtonian fluids in rectangular ducts were analyzed for all the modified H2 thermal boundary conditions around the periphery of the duct cross-section.

TL;DR: In this article, the dynamic response of porous media and packed beds systems to an arbitrary time varying inlet temperature is investigated analytically, and a two phase model is developed taking rigorously into account the fluid to solid heat capacity ratio.

TL;DR: In this paper, the two-dimensional transient temperature distributions in the core wall and in both the unmixed fluids are analytically determined, considering finite wall heat capacity (i.e., finite propagation speed of disturbances).

TL;DR: In this article, the authors presented a numerical solution to a natural convection problem concerning the use of a passive solar system for building heating purpose, which consists of a modification of the well-known Trombe-Michel passive system.
