The phrase "a bed of solid" is not correct in English as it is incomplete and lacks clarity.
It could be used in a context where you are describing a solid foundation or support, but it needs additional context to be meaningful.
Example: "The construction project requires a bed of solid material to ensure stability."
Alternatives: "a solid foundation" or "a firm base".
There, he said, he built a garden in a bed of solid rock.
The granulation is brought about when a bed of solid particles moves, with simultaneous intensive mixing, in the presence of a liquid phase.
The Greta gorge is still as Scott described it: The river runs with very great rapidity over a bed of solid rock, broken by many shelving descents, down which the stream dashes with great noise and impetuosity..
Another type of core configuration is the pebble bed reactor where the fuel consists of a bed of solid spheres through which coolant is circulated to remove the heat.
The rate of absorption with chemical reaction has been measured in a bed of solid spheres fluidized by upward flowing gas and irrigated by downward flowing liquid for different reactant concentrations in the liquid phase and different values of the liquid superficial velocity.
This paper presents the development of a novel mathematical model that describes spray injection and spreading into a fluidized bed of solid particles.
The model is developed by considering fluid flow over a stationary bed of solid particles of uniform thickness, which is resting on an inclined pipe wall.
Gasification medium is slowly flow through a fixed bed of solid particles.
Indeed, by modelling the foam as a packed-bed of solid spheres (with no adjustable constants), the mass-transfer coefficient in a bed of closely packed solid spheres was found to be in satisfactory agreement with the mass-transfer measured in the wet gas-liquid foam.
The paper analyses the dynamic aspects of the temperature field in a fluidised bed of solids particles (e.g., sand) in which a gaseous fuel is being burned.
A set of representative correlations for pressure drop across a fixed or expanding bed of solid particles was analysed with the aim of determining the applicability range of the capillary model.
