Numerical analysis of tunnelling with jet-grouted canopy

On the Application of Numerical Analysis in Tunnelling

At present tunnels tend to be analyzed on the basis of 2D finite element computations , because 3D analyses are considered to be extremely time consuming. As a result, 3D analyses are presently the domain of researchers. Consulting engineers will only perform 3DFEM analyses when facing complex geometries, e.g. tunnel joints or connections to underground stations, but not for straight-ahead tunn...

Numerical Simulation of Mechanized Tunnelling as Part of an Integrated Optimization Platform for Tunnelling Design

Mechanised tunnelling is characterised by a number of interacting components relevant for the excavation process (the soil including groundwater, the TBM, the linings, the support at the cutting face and the tail void) and by a staged process of excavation and lining erection. This imposes a considerable challenge for realistic modelling of the tunnelling process. The paper addresses recent adv...

Numerical study of a confined slot impinging jet with nanofluids

BACKGROUND Heat transfer enhancement technology concerns with the aim of developing more efficient systems to satisfy the increasing demands of many applications in the fields of automotive, aerospace, electronic and process industry. A solution for obtaining efficient cooling systems is represented by the use of confined or unconfined impinging jets. Moreover, the possibility of increasing the...
