We present an elastic model for B-form DNA with variable radius to study the elastic twist-stretch coupling of stretched DNA. In this model, only two strain variables as well as the changes in the energy of the hydrogen and covalent bonds of DNA...

Laminar flow and heat transfer of Al2O3/water nanofluid in the twisted-serpentine tube (TST) are investigated numerically. The numerical results are validated with data obtained from the empirical part of the study. The influences of three specific...

In this experimental study, hydrothermal characteristics of a U-tube equipped with twisted-tape inserts are

investigated experimentally. The twisting effects of side wall are also investigated for the U-tube as compared to

the smooth...
