Finite element simulation of transient laminar flow past a circular cylinder and two cylinders in tandem – Influence of buoyancy

B.S.V. Patnaik, P.A.A. Narayana, K.N. Seetharamu

Flow past an isolated circular cylinder and two cylinders in tandem is numerically simulated, under the influence of buoyancy aiding and opposing the flow. A modified velocity…

Active control of mixed convection in a rotating periodical two‐pass duct by using trailing‐wall transpiration

Jenn Jiang Hwang, Wei‐Jyh Wang

Deals with the flow reversal in a buoyancy‐opposed rotating duct that causes heat transfer deterioration. An active technique of trailing‐wall transpiration is adopted to check…

h‐adaptive finite element solution of high Rayleigh number thermally driven cavity problem

David A. Mayne, Asif S. Usmani, Martin Crapper

An h‐adaptive finite element code for solving coupled Navier‐Stokes and energy equations is used to solve the thermally driven cavity problem. The buoyancy forces are represented…

Numerical aerodynamic analysis of large buildings using a finite element model with application to a telescope building

Ramon Codina, Christopher Morton, Eugenio Oñate, Orlando Soto

Presents a numerical strategy for the aerodynamic analysis of large buildings, with an application to the simulation of the air flow within a telescope building. The finite…

Numerical analysis of a primary surface trapezoidal cross wavy duct

Esa Utriainen, Bengt Sundén

A three‐dimensional numerical study was conducted to assess the hydraulic and heat transfer performance of a primary surface type heat exchanger surface, called the trapezoidal…
