Fourier series-based modelling of the effects of thermal coupling on the transient dynamics of component loops in a Coupled Natural Circulation Loop
Prasanth Subramaniyan, Akhil Dass, Shivangi Tiwari +1
Energy efficiency in process industry and passive safety systems in nuclear power plants necessitate the use of buoyancy driven heat exchangers. The current study presents a 1-D nu…
Stability analysis of a single-phase rectangular Coupled Natural Circulation Loop system employing a Fourier series based 1-D model
Akhil Dass, Sateesh Gedupudi
A linear stability analysis of a single-phase Coupled Natural Circulation Loop (CNCL) is carried out using a Fourier series based 1-D model. A 3-D CFD study is undertaken to assess…
Fourier series based modeling of the dynamics of inclined closed loop buoyancy driven heat exchangers with conjugate effect
Akhil Dass, Sateesh Gedupudi
The modelling of the dynamics of inclined closed loop buoyancy driven heat exchangers with inclusion of the wall conduction effect at the heat exchanger is presented in the current…
On the heat transfer coefficient jump in tilted single-phase natural circulation systems
Akhil Dass, Sateesh Gedupudi
The present study investigates the effect of inclination on the buoyancy driven systems. A cavity, Natural Circulation Loop (NCL) and Coupled Natural Circulation Loop (CNCL) have b…
Modeling of pressure drop and heat transfer for flow boiling in a mini/micro-channel of rectangular cross-section
Shashwat Jain, Prasanna Jayaramu, Sateesh Gedupudi
In the present study, a 1-dimensional model is proposed to estimate the pressure drop and heat transfer coefficient for flow boiling in a rectangular microchannel. The present work…
1-D semi-analytical modeling and parametric study of a single phase rectangular Coupled Natural Circulation Loop
Akhil Dass, Sateesh Gedupudi
The study of heat exchangers with both the hot and cold fluid sides driven by buoyancy forces is an area of considerable interest due to their inherent passivity and non-existence…
1-D modelling and CFD study of the transient behaviour of a single phase Coupled Natural Circulation Loop
Akhil Dass, Sateesh Gedupudi
A Coupled Natural Circulation Loop (CNCL) consists of two Natural Circulation Loops (NCL) coupled thermally via a common heat exchanger. The transient modelling of such systems tha…
