Influence of Prandtl number on heat transfer of a flat vertical plate
Influence of Prandtl number on heat transfer of a flat vertical plate Abdul Razak Kaladgi; A.D. Mohammed Samee; M.K. Ramis International Journal of Nuclear Energy Science and Technology, Vol. 11, No. 3 (2017) pp. 272 - 290 Liquid metals, such as sodium (Na), lead (Pb), and lead-bismuth (Pb-Bi) eutectic (e), are considered as potential coolants for the fast spectrum nuclear reactors of the next generation. So the main objective of this paper is to study the heat transfer and fluid flow characteristics of liquid metal coolants flowing over a nuclear fuel element having uniform volumetric energy generation. Stream function vorticity formulation method was used to solve the full Navier Stokes equations governing the flow. The energy equation was solved using central finite difference method. For the two-dimensional steady state heat conduction and stream-function equation, the discretisation was done in the form suitable to solve using 'line-by-line Gauss-Seidel' solution technique whereas the discretisation of vorticity transport and energy equations was done using Alternating Direction Implicit (ADI) scheme. After discretisation the systems of algebraic equations were solved using 'Thomas algorithm'. The complete work was done by writing a well-validated indigenous computer code using C-language. The parameters considered for the study were: aspect ratio of fuel element, A<SUB align="right">r, conduction-convection parameter Ncc, total energy generation parameter Q<SUB align="right">t, and flow Reynolds number Re<SUB align="right">H. The results obtained can be used to minimise the maximum temperature in the fuel element (hot spots) and prevent its melting.

Fires caused by lightning strikes on hydrocarbon storage plants are a century-old, yet to be addressed, problem. In the era of hydraulic fracturing, or fracking, this is becoming an even more poignant issue for the fossil fuel industry.
