Flow Development in the Hydrodynamic Entrance Region of Tubes and Ducts

The Physics of Fluids, 1964
A new method of analysis has been devised for determining the developing laminar flow and corresponding pressure drop in the entrance region of tubes and ducts. The method is formulated in a general manner which applies to ducts of any cross section.

Flow in the Entrance Region of Ducts

The Physics of Fluids, 1969
A technique for the solution of an eigenvalue problem arising in entrance region flow is presented along with a simplification of the nonlinear transformation used with such problems. From this, certain other results are obtained.

Entrance region flow

AIChE Journal, 1965
AbstractThe results of rigorous numerical solutions of the general equations of motion are presented for isothermal, laminar, Newtonian flow in a tube entrance region for a uniform entrance velocity. Computed velocity profiles, entrance length, and pressure gradients are compared with previous theoretical and experimental results.

Entrance and exit dose regions for a clinac-2100c

International Journal of Radiation Oncology*Biology*Physics, 1993
While significant advances have taken place in confirming dose in homogeneous media and accounting for changes due to distant heterogeneities, interface dosimetry is still a dose assessment problem. The entrance and exit surfaces of the patient are a prime example where dose assessment is questionable, but important, in many clinical situations.Data ...

LAMINAR HEAT TRANSFER IN THE ENTRANCE REGION OF DUCTS

Numerical Heat Transfer, 1979
This paper presents a generally applicable approach to laminar heat transfer problems in the entrance region of ducts. Consideration is given to the general situation in which ducts have arbitrary but constant cross sections. The finite-element method is used in the simultaneous step-by-step integration of the momentum and energy equations.
